对GaP:N(Te,Zn)中束缚激子发光热猝灭的测量和分析表明,中性Te原子以“俄歇阻断”作用,在NN对发光猝灭温度相对于不掺施主和受主的GaP:N有所降低方面起了关键的影响。掺Te后孤立N发光峰的猝灭温度提高,则是由于增加了N原子上电子分布的几率。这支持了N束缚激子的Hopfield-Thomas-Lyneh模型。受主Zn的作用是使自由激子发光随温度升高而缓慢增强,对A峰猝灭的减缓可能也有贡献。
The measurement and analysis of the quenching quenching of bound excitons in GaP: N (Te, Zn) show that the neutral Te atoms act as “Auger blocking”, and the quenching temperature of NN relative to the undoped host and acceptor The main impact of GaP: N has been declining. The quenching temperature of the isolated N-luminescence peak after the addition of Te is increased due to the increased probability of electron distribution on the N atom. This supports the Hopfield-Thomas-Lyneh model of N-bound excitons. The role of the acceptor Zn is to allow the free excitons to glow slowly with increasing temperature, possibly contributing to the slowing down of the A-peak quenching.
