Photoacoustic investigations of thermal and electronic properties of single crystal Ge doped with Cr
(E D P Sciences, Les Ulis Cedex A, 2005)
A high purity single crystal Ge with a (1 1 1) orientation was doped with Cr. A thin film of Cr was evaporated and then diffused into Ge substrate. The photoacoustic PA amplitude and phase spectra were measured and numerically ...
