When a positive bias of 0.5 V is applied to the metal side of a Pt–Si junction, the junction has the capacitance of 0.25 pF. A bias of 1.5 V results in a capacitance of 0.05 pF. The junction area A = 10-5 cm2, and the temperature T = 300 K. The effective electron mass in Si is me* = 0.26 me. (a) Is the semiconductor of p- or n-type? What is the smallest value of the applied voltage at which the space-charge region in the semiconductor starts to appear? Is the metal work function bigger or smaller than the semiconductor’s? (b) What is the doping level of the semiconductor? (c) What

Types of Charge Carriers

A carrier is a type of object which carries a particular thing from one point to another point. For instance, people use different vehicles from one place to another, and the vehicle carries those people and acts as a carrier.
