Prepare yourself for this MCQ quiz on introduction to semiconductors. Semiconductors are meant by substances with properties somewhere between them. ICs(integrated circuits) as well as discrete electronic components, such as diodes and transistors, exist because of semiconductors. Common elemental semiconductors are known as silicon and germanium. Silicon is well-known of these. Silicon forms most of the integrated circuits. Let's see how much more you know! We wish you the best of luck!
Resistor-like properties of metal oxides.
Variable conductive properties of some materials.
The fact that electrons conduct better than holes.
Insulating properties of silicon and GaAs.
