Cherednichenko S, Rönnung F, Gol’tsman G, Kollberg E, Winkler D. YBa2Cu3O7-δ hot-electron bolometer mixer at 0.6 THz. In: Proc. 11th Int. Symp. Space Terahertz Technol.; 2000. p. 517–22.
Abstract: We present an investigation of hot-electron bolometric mixer based on a YBa 2 Cu 3 O 7-δ (YBCO) superconducting thin film. Mixer conversion loss of –46 dB, absorbed local oscillator power and intermediate frequency bandwidth were measured at the local oscillator frequency 0.6 THz. The fabrication technique for nanoscale YBCO hot-electron bolometer (HEB) mixer integrated with a planar antenna structure is described.
