In the solid-state physics of semiconductors, carrier generation and carrier recombination are processes by which mobile charge carriers (electrons and electron holes) are created and eliminated. Carrier generation and recombination processes are fundamental to the operation of many optoelectronic semiconductor devices, such as photodiodes, light-emitting diodes and laser diodes. They are also critical to a full analysis of p-n junction devices such as bipolar junction transistors and p-n junction diodes. The electron–hole pair is the fundamental unit of generation and recombination in inorganic semiconductors, corresponding to an electron transitioning between the valence band and the conduction band where generation of electron is a transition from the valence band to the conduction band and recombination leads to a reverse transition. (Wikipedia).

Introduction to Diode Rectifiers | What Is 3-Phase Power? -- Part 5
In 3-phase electrical power systems, the AC system is commonly connected to a DC system. The process of converting AC to DC is known as rectification. You will learn: - The operating principle of a single diode acting as a half-wave rectifier - How an H-bridge rectifier operates as a full

Reciprocity: Examples And Quantitative Confirmation
Reciprocity is a very remarkable and useful symmetry that exists in many different types of physical systems. Simply stated, if a system is driven at one point, and the response is detected at another point, the same response occurs if the source and receiver are interchanged. Linear p
