What are Semiconductors?

Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics).
- Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide.
Basic Composition of Semiconductors:

- The basic component of a semiconductor chip is a sliver of silicon.
- This silicon chip is etched with billions of microscopic transistors.
- Patterns on the chip are formed by specific minerals and gases.
- These patterns control the flow of electrical current and execute various computational instructions.
Varieties of Semiconductors:
- Higher nanometer value semiconductors find applications in automobiles and consumer electronics.
- Lower nanometer value semiconductors are used in devices like smartphones and laptops.
Application: Semiconductors are essential components found in nearly all modern electronic devices, including smartphones and Internet of things (IoT) devices.
