Development of an Inductive NIS Thermometer

Abstract

We have studied an inductive readout for normal metal-insulator-superconductor (NIS) tunnel junctions by using on-chip planar inductors and a DC SQUID (superconducting quantum interference device) to develop a sensitive and fast thermometer for studies of nanoscale heat conduction and bolometry. Our initial results show the feasibility of the concept, with a good sensitivity for temperatures below 1 K for aluminum as the superconductor when voltage biased close to the superconductor energy gap.

The coexistence of high piezoelectricity and superior optical absorption in Janus Bi2X2Y (X = Te, Se; Y = Te, Se, S) monolayers

“…7,8 Recently, piezoelectric materials have also been proven to enable acoustic waves to tunnel across a vacuum gap by producing macroscopic electric fields. 9 The unique energy conversion characteristics of piezoelectric materials give them huge development and application space. However, although inorganic materials such as piezoelectric ceramics have excellent piezoelectric properties, their brittleness or toxic lead content limits their application in flexible devices or consumer devices.…”
