2. Application of Semiconductor Physics &
Semiconductor
What is
Semiconductor :
Semiconductor devices are nothing but electronic components that
exploit the electronic properties of semiconductor materials, like as
silicon, germanium, and gallium arsenide, as well as organic
semiconductors.
3. Application of
Semiconductors:
Semiconductors are employed in the manufacture of various
kinds of electronic devices, including diodes, transistors,
and integrated circuits. Such devices have found wide
application because of their compactness, reliability,
power efficiency, and low cost.
4. Diodes:
Diodes is one of the simplest semiconductor
devices. There are many important
applications for diodes in electric and digital
circuits.
The efficiency is defined as the ratio of input AC to
the output DC.
It is defined as the amount of AC content in the
output DC.
A half wave rectifier allow current to flow during
half the AC cycle
A full wave rectifier both halve of the AC cycle.
Rectifier:
5. Transisto
rs:
A transistor is a semiconductor
device used to amplify or switch
electronic signals and electrical
power.
Integrated
Circuit:
Integrated circuit (IC), also called microelectronic
circuit, microchip, or chip, an assembly
of electronic components, fabricated as a single unit, in which
miniaturized active devices (transistors and diodes) and
passive devices (capacitors and resistors) and their
interconnections are built up on a thin substrate
of semiconductor material
6. Application of semiconductor in
industrial sectors
Microprocesso
r:
A microprocessor is a computer processor where the data
processing logic and control is included on a single integrated
circuit, or a small number of integrated circuits. The
microprocessor is a multipurpose, clock-driven, register-based,
digital integrated circuit that accepts binary data as input,
processes it according to instructions stored in its memory,
and provides results (also in binary form) as output.
7. Solar
Cell:
A solar cell is made of two types of semiconductors, called
p-type and n-type silicon. The p-type silicon is produced by
adding atoms—such as boron or gallium—that have one
less electron in their outer energy level than does silicon.
Because boron has one less electron than is required to form
the bonds with the surrounding silicon atoms, an electron
vacancy or “hole” is created.
