Native-oxide limited cross-plane thermal transport in suspended silicon membranes revealed by scanning thermal microscopy
International audienceBy thermally characterizing nanometer-thin suspended silicon membranes with various micrometric lengths in ambient conditions, we determine simultaneously the spatial resolution of our Wollaston-probe scanning thermal microscopy experiment, which probes an area of (285 nm)2, and the effective thermal conductivity of the membranes of 40 W.m-1.K-1. This value is smaller thanthe in-plane thermal conductivity measured using other techniques in vacuum (60 W.m-1.K-1), revealing that both cross-plane and in-plane heat conduction are strongly affected by the native oxide in ambient conditions. This work also underlines that high-thermal conductivity samples can be characterized by scanning thermal microscopy when micro-patterned
