Trifonov, A., Tong, C. E., Lobanov, Y., Kaurova, N., Blundell, R., & Gol’tsman, G. (2015). An investigation of the DC and IF performance of silicon-membrane HEB mixer elements. In Proc. 26th Int. Symp. Space Terahertz Technol. (40).
Abstract: We report on our initial development towards a 2x2 multi-pixel HEB waveguide mixer for operation at 1.4 THz. We have successfully fabricated devices comprising an NbN bridge integrated with antenna test structure using a silicon membrane as the supporting substrate. DC measurements of the test chips demonstrate critical current from 0.1 – 1mA depending on the size of device, with T c of around 10 K and ΔTc ~ 0.8 K.

Abstract: Температурная зависимость ширины линии ЭПР доноров Р в Si исследована в интервале концентрации ND=2.5⋅1017−9⋅1017см−3 и температур T=1.7−45 K на образцах с различной степенью компенсации основной примеси. Результаты согласуются с моделью обменного сужения линии при учете температурной зависимости обменного интеграла и тем самым исключают предлагавшийся ранее механизм сужения линии вследствие прыжкового движения электронов по примесным центрам.

Abstract: The possibility is considered of carrying out submillimeter-wave spectral investigations of semiconductors by means of a high resolution spectrometer with backward-wave tubes. Results of a study of the excitation spectra of small impurities, D-(A +) centers and free excitons in germanium are presented.

Abstract: The bolometer response to THz radiation from a weakly coupled GaAs/AlGaAs superlattice biased in the self-oscillations regime has been observed. The bolometer signal is modulated with the frequency equal to the fundamental frequency of superlattice self-oscillations. The frequency spectrum of the bolometer signal contains higher harmonics whose frequency is a multiple of fundamental frequency of self-oscillations.
