论文摘要
卤化物钙钛矿在照明后表现出缓慢的非辐射电子孔重组速率。 Chu等。 [Sci。 ADV。 6 7,EAAW7453(2020)]使用第一原理模拟的结果来争辩说,这是由晶体振动的性质产生的,并导致了震荡的读取台理论的分解。我们在晶体半导体中通过点缺陷对载体捕获的方法进行了突出显示缺陷。
Halide perovskites exhibit slow rates of non-radiative electron-hole recombination upon illumination. Chu et al. [Sci. Adv. 6 7, eaaw7453 (2020)] use the results of first-principles simulations to argue that this arises from the nature of the crystal vibrations and leads to a breakdown of Shockley-Read-Hall theory. We highlight flaws in their methodology and analysis of carrier capture by point defects in crystalline semiconductors.
