Measure the out-of-plane k of suspended thin film

  1. Jan 13, 2015 #1
    Hi there,

    Does anyone know if there is any method to measure the out-of-plane thermal conductivity of a suspended thin film? As the conventional way of measuring the out-of-plane thermal conductivity is to deposit the thin film on a thick substrate, but we want it suspended.

    Thanks in advance.

    Thanks for your reply.

    As most of TDTR method used previously was thin film on a substrate, I'm not sure whether it can be applied to suspended film condition. Also, I'm curious if 3 omega method can be applied to suspended thin film structure.
