Vi. Gavrilenko et al., INVERTED DISTRIBUTIONS OF HOT HOLES IN UNIAXIALLY STRESSED GERMANIUM, Semiconductor science and technology, 7(3B), 1992, pp. 649-651
Compressive stress is found to improve the characteristics of all type
s of hot hole masers and lasers in p-Ge. Effects of the uniaxial stres
s of p-Ge crystal on the FIR emission in both E parallel-to H and E pe
rpendicular-to H fields are discussed. Mechanisms of the influence of
uniaxial stress on the population inversion and the stimulated emissio
n of hot holes are revealed.
