Q: Answer-The material used in the fabrication of a transistor is –

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. The first transistors were made from germanium Ge. Silicon Si types currently predominate but certain advanced microwave and high performance versions now employ the compound semiconductor material gallium arsenide GaAs and the semiconductor alloy silicon germanium SiGe.
