| Year | 2016 | Publication | МАКС Пресс | Abbreviated Journal | |
| Volume | Issue | Pages | |||
| Keywords | programming, computer science | ||||
| Abstract | Первый том серии «Программирование: введение в профессию» включает две основные части. В первую часть книги вошли избранные сведения из истории вычислительной техники, обсуждение некоторых областей математики, непосредственно используемых программистами (таких как алгебра логики, комбинаторика, позиционные системы счисления), математических основ программирования (теория вычислимости и теория алгоритмов), принципы построения и функционирования вычислительных систем, начальные сведения о работе с командной строкой ОС Unix. Вторая часть посвящена начальным навыкам составления компьютерных программ на примере Free Pascal под ОС Unix. Материал ориентирован на изучение в будущем языка Си, так что, в частности, много внимания уделено работе с адресами и указателями, построению списков и других динамических структур данных; в то же время многие возможности Паскаля из рассмотрения исключены. Даются сведения о правилах оформления текстов программ, о тестировании и отладке. | ||||

Ultrafast time measurements by time-correlated single photon counting coupled with superconducting single photon detector | Type | Journal Article | ||
| Year | 2016 | Publication | Rev. Sci. Instrum. | Abbreviated Journal | |
| Volume | 87 | Issue | Pages | 053117 (1 to 5) | |
| Keywords | SSPD, SNSPD, TCSPC, jitter | ||||
| Abstract | Time resolution is one of the main characteristics of the single photon detectors besides quantum efficiency and dark count rate. We demonstrate here an ultrafast time-correlated single photon counting (TCSPC) setup consisting of a newly developed single photon counting board SPC-150NX and a superconducting NbN single photon detector with a sensitive area of 7 × 7 μm. The combination delivers a record instrument response function with a full width at half maximum of 17.8 ps and system quantum efficiency ~5% at wavelength of 1560 nm. A calculation of the root mean square value of the timing jitter for channels with counts more than 1% of the peak value yielded about 7.6 ps. The setup has also good timing stability of the detector–TCSPC board. | ||||

Two-dimensional plasmons in lateral carbon nanotube network structures and their effect on the terahertz radiation detection | Type | Journal Article | ||
| Year | 2016 | Publication | J. Appl. Phys. | Abbreviated Journal | J. Appl. Phys. |
| Volume | 120 | Issue | 4 | Pages | 044501 (1 to 13) |
| Keywords | carbon nanotubes, CNT detectors, plasmons | ||||
| Abstract | We consider the carrier transport and plasmonic phenomena in the lateral carbon nanotube (CNT) networks forming the device channel with asymmetric electrodes. One electrode is the Ohmic contact to the CNT network and the other contact is the Schottky contact. These structures can serve as detectors of the terahertz (THz) radiation. We develop the device model for collective response of the lateral CNT networks which comprise a mixture of randomly oriented semiconductor CNTs (s-CNTs) and quasi-metal CNTs (m-CNTs). The proposed model includes the concept of the collective two-dimensional (2D) plasmons in relatively dense networks of randomly oriented CNTs (CNT “felt”) and predicts the detector responsivity spectral characteristics exhibiting sharp resonant peaks at the signal frequencies corresponding to the 2D plasmonic resonances. The detection mechanism is the rectification of the ac current due the nonlinearity of the Schottky contact current-voltage characteristics under the conditions of a strong enhancement of the potential drop at this contact associated with the plasmon excitation. The detector responsivity depends on the fractions of the s- and m-CNTs. The burning of the near-contact regions of the m-CNTs or destruction of these CNTs leads to a marked increase in the responsivity in agreement with our experimental data. The resonant THz detectors with sufficiently dense lateral CNT networks can compete and surpass other THz detectors using plasmonic effects at room temperatures. | ||||

Travelling-wave single-photon detectors integrated with diamond photonic circuits: operation at visible and telecom wavelengths with a timing jitter down to 23 ps | Type | Conference Article | ||

| Volume | 9750 | Issue | Pages | 135-142 | |

| Abstract | We report on the design, fabrication and measurement of travelling-wave superconducting nanowire single-photon detectors (SNSPDs) integrated with polycrystalline diamond photonic circuits. We analyze their performance both in the near-infrared wavelength regime around 1600 nm and at 765 nm. Near-IR detection is important for compatibility with the telecommunication infrastructure, while operation in the visible wavelength range is relevant for compatibility with the emission line of silicon vacancy centers in diamond which can be used as efficient single-photon sources. Our detectors feature high critical currents (up to 31 μA) and high performance in terms of efficiency (up to 74% at 765 nm), noise-equivalent power (down to 4.4×10-19 W/Hz1/2 at 765 nm) and timing jitter (down to 23 ps). | ||||

| Title |
The prospects of using the radiation for the assessment of corneal and scleral hydration | Type | Abstract | ||
| Year | 2016 | Publication | Acta Ophthalmol. | Abbreviated Journal | Acta Ophthalmol. |
| Volume | 94 | Issue | Pages | ||
| Keywords | BWO, avalanche transit‐time diode, medicine, biology | ||||
| Abstract | Purpose An adequate water balance (hydration extent) is one of the basic factors of normal eye function, including its external shells – the cornea and the sclera. THz systems creating images in reflected beams are likely to become ideal instruments of noninvasive testing of corneal and scleral hydration degree as THz radiation is highly sensitive to water content. The paper aims at studying the transmittance and reflectance spectra of the cornea and the sclera of rabbit and human eyes, as well as those of the whole rabbit eye, in the frequency range of 0.13–0.32 THz. Methods The experiments were carried out on 3 corneas and 3 rabbit scleras, 2 whole rabbit eyes, and 3 human healthy adult scleras using a specially developed THz system based on reliable and easy‐to‐use continuous wave sources: a backward‐wave oscillator and an avalanche transit‐time diode. Results The transmittance spectra of the cornea and the sclera and the dependence of the reflection coefficient of these tissues in THz range on water percentage content were determined. Comparison of the rabbit cornea hydrated from 73.2% to 76.3% concentration by mass demonstrated an approximately linear relationship between THz reflectivity and water concentration. The decrease of free water concentration by 1% leads to a drop of the reflectance coefficient by 13%. The parameters studied displayed noticeable differences between the sclera and the cornea of rabbits and between rabbit sclera and human sclera. Conclusions Preliminary results demonstrate that the proposed technique, based on continuous THz radiation, may be used to create a device for noninvasive testing of corneal and scleral hydration, which has good potential of wide‐scale practical application.

| Title |
The influence of the diffusion cooling on the noise band of the superconductor NbN hot-electron bolometer operating in the terahertz range | Type | Journal Article | ||
| Year | 2016 | Publication | Tech. Phys. Lett. | Abbreviated Journal | |
| Volume | 42 | Issue | 6 | Pages | 563-566 |
| Keywords | HEB, noise bandwidth, conversion gain bandwidth, noise temperature, Andreev reflection | ||||
| Abstract | Results of an experimental study of the noise temperature (Tn) and noise bandwidth (NBW) of the superconductor NbN hot-electron bolometer (HEB) mixer as a function of its temperature (Tb) are presented. It was determined that the NBW of the mixer is significantly wider at temperatures close to the critical ones (Tc) than are values measured at 4.2 K. The NBW of the mixer measured at the heterodyne frequency of 2.5 THz at temperature Tb close to Tc was ~13 GHz, as compared with 6 GHz at Tb = 4.2 K. This experiment clearly demonstrates the limitation of the thermal flow from the NbN bridge at Tb â‰<aa> Tc for mixers manufactured by the in situ technique. This limitation is close in its nature to the Andreev reflection on the superconductor/ metal boundary. In this case, the noise temperature of the studied mixer increased from 1100 to 3800 K. | ||||
