The PN junction diode is one of the most important and widely used semiconductor devices in electronics. It is created by joining a P-type semiconductor and an N-type semiconductor within a single crystal structure. This simple yet powerful device allows electric current to flow easily in one direction while offering very high resistance to current […]
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 […]
