Which of the following correctly describes a diode?
Which of the following correctly describes an n-type semiconductor?
A - junction consists of 2 different types of semiconductors: a -type semiconductor and an -type semiconductor. The -type semiconductor has free electrons than a pure semiconductor, and the -type semiconductor has free electrons than a pure semiconductor. Where the -type and -type semiconductors are joined, electrons from the semiconductor recombine with electron holes from the semiconductor, creating a region between the two materials which acts as a/an .
