Applications of n-type and p-type semiconductors
- n-type and p-type semiconductors finds a great use in manufacturing electronic components.
- Diode is a combination of n-type and p-type semiconductors extensively used as a rectifier.
- Transistors are manufactured by keeping a layer of one type of semiconductor between two layers of another type of semiconductor.
- npn and pnp type of transistors are used to detect or amplify radio or audio signals.
- The solar cell is an efficient photo-diode used for conversion of light energy into electrical energy.
- Gallium arsenide (GaAs) semiconductors have very fast response and have transformed the design of semiconductor devices.
- Transition metal oxides show marked differences in electrical properties.
- TiO, CrO2 and ReO3 behave like metals.
- Rhenium oxide, ReO3 resembles metallic copper in terms of its conductivity and appearance.
- Certain other oxides like VO, VO2, VO3 and TiO3 exhibit metallic or insulating properties depending on temperature.
