Hystersis like behaviour in Thin Films with heating-cooling cycle

TL;DR

This paper investigates how temperature gradients in thin films with finite thermal conductivity cause hysteresis-like resistance behavior during heating and cooling cycles.

Contribution

It derives the temperature distribution in thin films and explains the hysteresis-like resistance behavior due to thermal gradients during heating and cooling.

Findings

Temperature distribution along the film thickness is derived.

Hysteresis-like behavior observed in resistance during heating-cooling cycles.

Finite thermal conductivity causes temperature gradients leading to hysteresis.

Abstract

The expression of temperature distribution along a film thickness is derived and distribution of temperature in the film as the substrate is heated is shown. The variation of film resistance with different substrate temperature is calculated and the existence of temperature gradient along the film thickness with finite thermal conductivity leads to hysteresis like behaviour on heating-cooling the film.
