Figure 1
(a) Scanning electron microscopy (SEM) image of a typical Ge micro-bridge used in the experiments with a sketch of the scattering geometry indicating the incoming and outgoing wavevectors for the two probed Bragg reflections. (b) The same bridge structure as that shown in (a) with a colored plane indicating the region scanned along the sample surface and three points where measurements described in the text have been performed.  [article HTML]
