Basal plane thermal conductivity of thin germanane layers

Basal plane thermal conductivity of thin germanane layers

The thermal conductivity of thin Germanane (GeH) layers was measured using suspended micro-devices with integrated heaters and thermometers. The thermal contact resistance of the GeH samples suspended on the measurement devices was determined from the measured thermal resistance values of samples wi...
