Measurements of the in-plane thermal conductivity of thin films using a microstructured heater and sensor arrangement — •David Hartung, Achim Kronenberger, Steve Petznick, Torsten Henning, Bruno K. Meyer, and Peter J. Klar — I. Physikalisches Institut, Justus-Liebig-Universität Gießen, Germany

The aim of this work is to characterise the lateral heat flow in a thin semiconductor layer on a glass substrate. Cover-glass is used for the heater and sensor arrangement. The masurement area is 0.5 mm × 0.5 mm where sensor and heater are deposited. A broad Au wire along the middle axis of this measurement area serves as the electric heater, three narrow Au wires at different distances from, but parallel to the heater wire, serve as temperature sensors. The arrangement was defined by photolithography on to the grass-substrate. Thin films of insulating ZnS and ZnO are deposited on to the measurement by RF-sputtering. First results of the measurements will be presented.
