由于量子阱中的浅施主杂质的研究对杂质能级的性质以及量子阱本身性质的研究都提供了有用的信息 ,因而近来对极性半导体量子阱中的极化子 (不仅是自由极化子而且也对束缚极化子 )的行为的研究受到人们的重视 .不过以前人们将注意力仅仅放在类氢施主杂质上 [1 ,2 ] .显然考虑类 Since the study of shallow donor impurities in quantum wells provides useful information on the properties of impurity levels and the nature of the quantum wells, recent studies on polaron quantum wells, not only free-polarons But also for the binding polaron.) However, attention has been paid only to hydrogen-like donor impurities [1, 2]
