摘要：

Studies of the luminescence spectra of Si1-xGex/Si quantum wells with a low Ge content have been carried out in a wide pumping power range. It was shown that a Si1-xGex/Si quantum well spectrum variation observed at low temperatures and high pumping powers is caused by cooperative effects-formation of the electron-hole liquid and multiexciton complexes in quantum wells.
