Abstract

Bolometers based on the superconductor–insulator–normal-metal–insulator–superconductor (SINIS) structure with an absorber suspended above the substrate are developed, fabricated, and experimentally studied in the terahertz frequency range. In contrast to the previously studied bolometers with an absorber located directly on the substrate, the real bolometric mode of operation is achieved, i.e., there is more than one excited electron per quantum of electromagnetic radiation (the quantum efficiency is larger than 1). A quantum efficiency of fifteen electrons per quantum of radiation with a frequency of 350 GHz was achieved in the studied bolometers.

基于SINIS结构的悬浮吸收剂测振的量子响应。

摘要

在太赫兹频率范围内，开发了基于超导体－绝缘体－正常金属－绝缘体－超导体（SINIS）结构的吸收计，该吸收计悬挂在基板上方，并进行了实验研究。与先前研究的具有直接位于基板上的吸收器的辐射热计相反，实现了真正的辐射热运算模式，即每个电磁辐射量子中有一个以上的激发电子（量子效率大于1）。在所研究的辐射热测量计中，每个辐射量子的15个电子的量子效率为350 GHz。
