Studies of the luminescence spectra of Si 1รx Ge x /Si quantum wells with a low Ge content have been carried out in a wide pumping power range. It was shown that a Si 1รx Ge x /Si quantum well spectrum variation observed at low temperatures and high pumping powers is caused by cooperative effects-fo
