Drift current and diffusion current are two fundamental mechanisms of charge transport in semiconductors. These concepts form the basis of semiconductor physics and are extremely important for understanding the operation of devices such as p-n junction diodes, transistors, LEDs, solar cells, MOSFETs, and integrated circuits. In semiconductors, electric current is produced not only by the […]
