WebRecombination through defects, previously known as Shockley-Read-Hall (SRH or RHS) recombination, occurs via a trap level or defect energy level in the band gap. Defect recombination is a two-step process:: An electron (or hole) is trapped by an energy state in the forbidden region which is introduced through defects in the crystal lattice. Web11 Apr 2024 · Shockley-Read-Hall (SRH) Recombination SRH复合. 声子跃迁发生在半导体的禁止间隙内存在陷阱(或缺陷)的情况。这本质上是一个两步的过程,其理论首先由肖克利和Read ,然后由Hall 推导出(简说成肖克利复合模型)。

WebSRH模型是通过单一复合中心的间接复合模型。描述这种复合过程的基本理论是由Hall以及Shockley与Read于1952年提出来的,即后来广为引用的SRH模型。

Web23 Aug 2024 · Those are the Shockley-Read-Hall (SRH) process and auger recombination. SRH is recombination through atomic trap's in the lattice. These traps are caused by impurities or defects within the lattice which create intermediate bands within the band gap. This converts the electron/hole energy into phonons (lattice vibrations/heat). Websrh就是通过中间能级复合,相当于本来电子直接跳下去太难,找了个台阶,分两步跳下去。 俄歇复合是跟能量有关的,导带的电子要跑去价带,释放的能量就传给了其他导带的电子,这样就不会发出光子 lc0352 引用回帖: 3楼:Originally posted by yanyuan55at 2016-09-02 12:26:47 srh就是通过中间能级复合,相当于本来电子直接跳下去太难,找了个台阶,分两 …
