Fermi level for p type semiconductor
http://technology.whu.edu.cn/info/1015/1890.htm WebWhat is Fermi Level in Semiconductors? Fermi level (denoted by EF) is present between the valence and conduction bands. It is the highest occupied molecular orbital at absolute zero. The charge carriers in this state have their own quantum states and generally do not interact with each other.
