what are the applications of P type and N type systems?
Answers
Explanation:
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.
