Semiconductor Theory is a course that delves into the fundamental principles and physics of semiconductors, which are materials essential for modern electronics. The course typically covers topics such as:

• Atomic Structure of Semiconductors: Understanding the crystal lattice structure and how atoms are arranged in semiconductor materials (like silicon or gallium arsenide).
• Band Theory: The concept of energy bands (valence and conduction bands) and how they determine electrical conductivity in materials.
• Charge Carriers: Electrons and holes, and how they move through the semiconductor to create current.
• Doping: Introducing impurities into semiconductors to enhance their electrical properties (p-type and n-type semiconductors).
• PN Junctions: The behavior of semiconductors at the interface of p-type and n-type materials, forming the basis of diodes and transistors.
• Carrier Transport: Mechanisms of carrier movement, including drift, diffusion, and recombination.
• Semiconductor Devices: Introduction to basic electronic components like diodes, transistors, and integrated circuits.

The course prepares students to understand the behavior of semiconductor devices and their applications in electronics.
