Semiconductors are the foundation of modern electronics and are widely used in devices such as diodes, transistors, integrated circuits, solar cells, sensors, and microprocessors. Based on the purity and conductivity characteristics, semiconductors are mainly classified into two types Intrinsic Semiconductor and Extrinsic Semiconductor. Understanding the difference between intrinsic and extrinsic semiconductors is extremely important in […]
In this article, we will explore intrinsic semiconductors, including their definition, crystal structure, energy band diagram, characteristics, advantages, disadvantages, and applications. An intrinsic semiconductor is a pure semiconductor material without any significant impurity atoms added to it. In intrinsic semiconductors, the number of free electrons and holes are naturally generated due to thermal energy and […]
Energy band theory of solids explains why some solids conduct electricity easily, why some do not, and why others behave in-between. Classical physics could not explain electrical conduction fully, but quantum mechanics and band theory together provide a complete picture. Solids are materials in which atoms are closely packed in a regular or irregular arrangement. […]
