Characterization of superconducting FeSe0.5Te0.5 hot electron bolometer

Characteristics of superconducting FeSe _0.5 Te _0.5 hot electron bolometer are reported. The superconducting FeSe _0.5 Te _0.5 film is grown by pulsed laser deposition on MgO substrate, and its transition temperature and complex conductivity indicate that the film quality is good enough for hot electron bolometer. We then fabricate hot electron bolometer based on the superconducting FeSe ₀ . ₅ Te ₀ . ₅ film, and study the resistive transition curve and its current-voltage characteristics.
