The electronic and optical properties of BiFeO3 (BFO) crystal are investigated at 300 K and 1000 K, via density functional theory (DFT).The relative crystal surfaces include (001), (101) and (111).As the results shown of calculated spin-partial density of states (PDOS), the temperature influences the polarizations of BiFeO3 crystal.These are related to the electronic and optical properties.Therein, at 300 K, BFO has the highest optical property on (001), and on (111) at 1000 K.The reasons of the electronic property and optical spectrum were discussed.

在企業管理实践中,常常会遇到员工请求企业开具各种虚假证明之事,HR有时考虑到员工确实有“实际困难”,出于好心,自以为可以通过“举手之劳”帮员工一把;甚至有些员工直接找到老板,老板大笔一挥签字“同意”,HR只能硬着头皮开出证明……殊不知,类似这种开具虚假证明的行为,往往会给企业带来无谓的用工风险,无论是HR还是其他部门负责人,都应该谨慎对待,切莫为了逞一时之能,引火上身。虚假收入证明 2016年1
