Led principle working and construction
NettetWorking of Zener Diode. The Zener diode can operate in both forward and reverse bias. In forward bias, it acts as a normal diode with nominal forward voltage drop and a large current flow. While in reverse bias, it blocks current flow until the applied voltage reaches the Zener breakdown voltage. This region is known as the Zener breakdown ...

NettetWorking Principle Of LED The working principle of the Light emitting diode is based on the quantum theory. The quantum theory says that when the electron comes down from the higher energy level to the lower energy level then, the energy emits from the photon. The photon energy is equal to the energy gap between these two energy levels. Nettet28. jun. 2024 · LASER Diode Construction. The construction of a laser diode can be done using different materials like metal contact, p-type material, n-type material & intrinsic layer. The input terminals of this are connected toward metal plates which are inserted into the p-type and n-type layers. An alternative name of this diode is Homojunction Laser …
