半導(dǎo)體中摻雜元素的binding energy和PL中譜峰位置有什么關(guān)系?或者說復(fù)合機(jī)理
|

關(guān)于半導(dǎo)體中的PL和摻雜元素的binding energy的關(guān)系! 看文獻(xiàn)時(shí)發(fā)現(xiàn),對(duì)于半導(dǎo)體中參雜元素 If we assume a bound exciton binding energy of - 3 meV then the 0.795 eV peak would be separated from the band edge by 6 meV. The effective mass donor binding energy in In0.53 Ga.0.47 As is 3 meV; however, from luminescence measurements a binding energy of -7 meV is deduced. We therefore assign the 0.795 eV peak to a donor-to-valence band transition.? 之前也有文獻(xiàn)中談到過C、Zn等摻雜元素的binding energy,但是一直沒搞清楚binding energy和PL譜有什么關(guān)系,PL中峰位是怎么確定出來的? 求大神指導(dǎo)呀。!不甚感激。! |
