EESM5200 (L2) Part II: Topic 4 - MOS Capacitor with a Source
多重下拉选择题
It is known that the incremental charges ΔQ of a MOS capacitor consists of p-type silicon substrate with a source come from different sources. For the different regions given in the figure below, indicate the source of excess charges in Region 1: Region 1: holes from the substrate Region 2: negative ions from the substrate Region 3: electrons from the source

To tackle this question, I will examine what each region in a MOS capacitor represents in terms of charge sources.
Region 1: holes from the substrate
This region is described as containing holes from the substrate. In a p-type substrate, the majority carriers are holes. Under the appropriate gate bias, the interfacial region can accumulate holes, which originate from the substrate itself.......Login to view full explanation登录即可查看完整答案
