However, there has been criticism that sports such as football (soccer) and baseball are doing nothing about the issue, and letting athletes implicated in doping away unpunished.
Suppose that the semiconductor initially is charge neutral, with the charge due to holes exactly balanced by the negative charge due to acceptor doping impurities.
The use of transmutation doping of some semiconductors: the transmutation of host atoms into doping atoms by the nuclear capture of thermal neutrons. 4.
