InP中皮秒快速现象
Picosecond phenomena in InP
【摘要】 利用测量瞬态反射谱的方法,探索了掺硫、铁、锌以及非掺杂的InP中载流子寿命。观察到非掺杂InP中载流子寿命最长约60ps;掺锌Inp中载流子寿命38Ps居中;掺硫和掺铁的寿命最短约1ps。掺硫、铁和锌的InP中载流子寿命下降,是由于掺杂引入了复合中心。这一结果已被喇曼光谱所证实。
【Abstract】 Carrier lifetime in( S,Fe,Zn) doped InP and undoped InP has been investigated using the method of measuring transient reflectivity,which reveals a significant reduction of carrier lifetime from 60 ps in the unintentionally doped InP to about 1 Ps in(S,Fe) doped InP,38 ps in the Zn- doped.Doped InP carrier lifetime is shorter than undoped InP,because S,Fe and Zn serve as recombination and trapping centers.Raman study was used to confirm these results.
