中文摘要	(in, cr)as ferromagnetic semiconductor quantum dots (qds) were grown by molecular beam epitaxy on gaas (001) substrates. the growth temperature effects on structure and magnetism of the qds were investigated systematically. the cr(2+)3d(4) states and quantum confined effect are assumed to play an important role in the room-temperature ferromagnetism of (in, cr)as qds.
