The effect of ion irradiation on the strain in GexSi1-x strained layer
s is examined as a function of ion-fluence and irradiation temperature
. It is shown that irradiation at room temperature causes an increase
in the perpendicular strain whereas irradiation at elevated temperatur
es causes a decrease in the perpendicular strain. In both cases, subse
quent thermal annealing reduces the damage induced component of the st
rain. This behaviour is discussed in terms of the nature of the radiat
ion damage produced in the different temperature regimes.
