A group of materials that conduct electricity better than an insulator but less efficient than metal conductors.
Elements commonly used as semiconductors include silicon, germanium and selenium.
Process of adding small amounts of foreign atoms such as antimony and boron atoms.
Types of semiconductors
It is obtained when the p-type and n-type semiconductors are combined.
It acts as a tool that allows the current to flow in one direction only.
The diode works in two ways:
The depletion layer shrinks, R decreases
The junction voltage decreases
The supplied V is higher than the junction voltage
Current flows
Reverse-biased
The depletion layer thickens, R increases
The junction voltage increases
The supplied V is lower than the junction voltage
Current does not flow
