Oxygen depleted semiconducting Y-Ba-Cu-O exhibits an amorphous phase ( $a$ -YBCO), obtained at low deposition temperature (150 °C), which can be applied to fast uncooled near-infrared or THz detection. In the first part, we investigate room temperat

Hot electron bolometers (HEB) exploiting the properties of the high-TC superconductor (HTS) Y-Ba-Cu-O, are offering a competitive alternative to THz Schottky mixers, which require moderate cooling (e.g., 60 to 80 K). This arises from the HTS HEBs exp

The well known Y-Ba-Cu-O superconductor (oxygen rich) material also exhibits a semiconducting phase (oxygen depleted), which offers in its amorphous form (a-YBCO), an attractive solution for the easy fabrication of room temperature thermal radiation

Hot electron bolometers (HEB) made from high-TC superconducting YBa2Cu3O7⁻x (YBCO) oxide nano-constrictions are promising THz mixers, due to their expected wide bandwidth, large mixing gain, and low intrinsic noise. The challenge for YBCO resides,
