Abstract
The paper reports measurements of electron-beam-induced current contra st c vs. temperature T and beam current I(b) for two misfit dislocatio ns in a p-type Si/SiGe sample. It is demonstrated that the different b ehaviour observed can be explained on the basis of the Shockley-Read-H all recombination theory. The activity of the dislocation with dc(T)/d T>0 is controlled by deep centres while that of the other dislocation having dc(T)/dT<0 indicates shallow centres lying about 0.075 eV from the band edge.
