The magnitude of the charge of a hole is

### Right Answer is: Equal to that of an electron

#### SOLUTION

The magnitude of the charge of a hole is Equal to that of an electron.

• Heavily doped semiconductors tend to behave in a similar fashion as a metal having a large number of charge carriers, i.e., electron-hole pairs.
• Both of these charge carriers are equally responsible for conduction in their respective bands.
• When an electron is missing from this structure the bond has one electron less thus termed as a hole in the bond.
• The atom with one electron missing from its outermost orbit may be termed as +ve charged ion.
• Similarly, the structure may have an excess electron, thus simulating the condition of -ve charged ion.
• The holes (vacancies of electrons) may move from ion to ion in the crystal and produce the effect of motion of +ve charge (the hole).
• Each hole has a charge equal to that of an electron, in magnitude.
