Polarization of low temperature photoluminescence induced in germanium by deformation
Alekseev A.S., Galkina T.I., Penin N.A.
The polarization of recombination radiation of free excitons and electron-hole drops (EHD) in germanium at 1.8-5 *K under conditions of uniaxial compression is investigated. It is observed that the degree of polarization of the radiation of the free excitons and of the condensed phase of the excitons have different pressure dependences.
