Title Direct detection effect in small volume hot electron bolometer mixers Type (down) Journal Article
Year 2005 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 86 Issue 16 Pages 163503 (1 to 3)
Keywords HEB, mixer, direct detection effect
Abstract We measure the direct detection effect in a small volume (0.15μm×1μm×3.5nm)(0.15μm×1μm×3.5nm) quasioptical NbN phonon cooled hot electronbolometermixer at 1.6THz1.6THz. We find that the small signal sensitivity of the receiver is underestimated by 35% due to the direct detection effect and that the optimal operating point is shifted to higher bias voltages when using calibration loads of 300K300K and 77K77K. Using a 200GHz200GHzbandpass filter at 4.2K4.2K the direct detection effect virtually disappears. This has important implications for the calibration procedure of these receivers in real telescope systems.

Title Low noise hot-electron bolometer mixers for terahertz frequencies Type (down) Journal Article
Year 2008 Publication J. Low Temp. Phys. Abbreviated Journal J. Low Temp. Phys.
Volume 151 Issue 1-2 Pages 575-579
Keywords HEB, mixer, gain bandwidth, MgB2
Abstract Hot-electron bolometer (HEB) mixers are used in many low noise heterodyne radio astronomical receivers. Their noise temperature is at the level of 10–15 times the quantum limit. However, their gain bandwidth is a serious limiting factor. Here we review the state of the art of the HEB mixers gain bandwidth for different materials and substrates. We compare the gain bandwidth of HEB mixers made on bulk substrates and thin membranes. Finally, results for MgB2 thin films for broadband HEB mixers are discussed.
