当半导体重掺杂时,费米能级进入导带,本征光吸收边向高能方向移动的现象称为Burstein-Moss效应。通常发生在半导体重掺杂时。
MOSS-BURSTEIN EFFECT (Expt. B1O) The Moss-Burstein effect results from the Pauli Exclusion Principle and is seen in semiconductors as a shift with increasing doping of the band-gap as defined as the separation in energy between the top of the valence band and the unoccupied energy states in...
氩气流中退火的薄膜进行透射,反射和Hall效应的测量和分析发现,随着衬底温度的降低,载流子浓度呈上升趋 势,而吸收边呈现先是"蓝移"然后"红移"的现象.从理论上阐述了高浓度的点缺陷对CIO氧化物薄膜的能带产生 的重要影响,这些影响主要体现在带尾的形成,Burstein-Moss(B—M)漂移和带隙收缩.另外,衬底温度的变化将对...
