Test Your Knowledge on Semiconductor Materials

What is the difference between an insulator and a conductor? An insulator is a material that does not allow electrons to flow freely through it. Semiconductors, on the other hand, are materials that can be made to act like either insulators or conductors under certain circumstances. Silicon is the most well-known semiconductor material, and our ability to finely control its insulating and conducting properties has led to the development of modern marvels like computers and mobile phones.
