Sub Topic Name : P-Type Semiconductor |
Electronic components that exploit the electronic properties of semiconductor materials, principally silicon, germanium, and gallium arsenide, as well as organic semiconductors.
Semiconductor
Silicon (Si) is the most widely used material in semiconductor devices.
What is N-type Semiconductor?
Key Words | Definitions (pref. in our own words) |
---|---|
p-type semiconductors. | Semiconductors doped in this way are termed p-type semiconductors. |
Gadgets | How it can be used |
---|---|
microprocessors | All transistor types can be used as the building blocks of logic gates, which are fundamental in the design of digital circuits. Transistors act as on-off switches; in the MOSFET, for instance, the voltage applied to the gate determines whether the switch is on or off. |
Building circuits.
Digital circuits.
Examples | Explainations |
---|---|
Solar cell | Electrical device that converts the energy of light directly into electricity by the photovoltaic effect. |
The majority charge carriers are positive holes.
Electron-accepting levels just above the top of the valence band, causes more holes to be introduced into the valence band.
