Experimental Measurement of the Time Constant of Cryogenic Sensors Based on Graphene and Nanotubes

Abstract

This paper presents an experimental measurement of the time constant that characterizes cryogenic microsensors based on nanomaterials. Two resistive structures designed with carbon nanotubes (s-CNT) and graphene layers (G) were developed and tested. The measurements were made by applying a step function in temperature to the sensors by immersing them in a liquid nitrogen bath (77.15 K).
