WebA hot point probe is a method of quickly determining whether a semiconductor sample is n-type or p-type. The sample is probed using a voltmeter or ammeter and a heat source, such as a soldering iron, is placed on one of the leads. The heat will cause charge carriers ( electrons in n-type, holes in p-type) to move away from the lead. WebJun 29, 2024 · Conductivity. In P-type semiconductors, the conductivity is due to the presence of holes. The conductivity in the N-type semiconductor is due to the presence of electrons. Fermi level. In a P-type semiconductor, the fermi level lies between the acceptor energy level and the valance band.
