Description
Semiconductors have always been known for their use in the production of electronic devices and electronic device components. This quiz in physics will help you understand what semiconductors are, and their types but we will be concentration on what these semiconductors are. This quiz is exam standard and good for any student preparing for a test or exams.
A semiconductor can be defined as a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. These substances are used in the manufacture of various kinds of electronic devices, hence semiconductor electronics, including diodes, transistors, and integrated circuits. There are two categories of semiconductors, Intrinsic and extrinsic semiconductors. Intrinsic semiconductors are those we will refer to as pure while extrinsic semiconductors are impure.
Knowledge of these quizzes is important even to our practical life as an economy. So take the quiz and learn more about semiconductors.
Enjoy!
