PY - 1999 DA - 1999// TI - Noise temperature of an NbN hot-electron bolometric mixer at frequencies from 0.7 THz to 5.2 THz JO - Supercond. Sci. Technol. SP - 748 EP - 750 VL - 12 IS - 11 KW - NbN HEB mixers AB - We report on noise temperature measurements of an NbN phonon-cooled hot-electron bolometric mixer in the terahertz frequency range. The devices were 3 nm thick films with in-plane dimensions 1.7 × 0.2 µm2 and 0.9 × 0.2 µm2 integrated in a complementary logarithmic-spiral antenna. Measurements were performed at seven frequencies ranging from 0.7 THz to 5.2 THz. The measured DSB noise temperatures are 1500 K (0.7 THz), 2200 K (1.4 THz), 2600 K (1.6 THz), 2900 K (2.5 THz), 4000 K (3.1 THz), 5600 K (4.3 THz) and 8800 K (5.2 THz).
