why electronic devices are made of semiconductor materials?
Electronic devices are made of semiconductor materials due to several reasons:
1. Control of electrical conductivity: Semiconductor materials have the unique property of having electrical conductivity that can be controlled. By adding impurities or doping the semiconductor material, the conductivity can be adjusted, making them ideal for creating electronic components like transistors.
2. Small size and compactness: Semiconductor materials allow for the creation of small and compact electronic devices. Due to their small size, semiconductors enable the miniaturization of components, making it possible to pack a large number of transistors, resistors, and capacitors into a small space, leading to the development of smaller and more portable devices.
3. Efficiency: Semiconductor devices are known for their high efficiency compared to other materials. They require low power to function, which helps in reducing energy consumption and increasing the battery life of electronic devices.
4. Switching capabilities: Semiconductors have the ability to switch between conducting and non-conducting states easily. This property enables the creation of digital electronic circuits, which are essential for computer systems and other digital devices.
5. Compatibility with silicon technology: Silicon, one of the most commonly used semiconductor materials, has excellent compatibility with the existing fabrication technology. This compatibility allows for the mass production of semiconductor devices at a low cost, making them economically viable for the electronics industry.
Overall, semiconductor materials provide the necessary properties and characteristics required for creating efficient, compact, and versatile electronic devices.
