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.
