Types of Optoelectronic Devices

Types of Optoelectronic Devices: Although light-emitting diodes and photodiodes are not quantum-mechanical devices in the Types of Optoelectronic Devices, they are semiconductor devices closely associated with lasers. It is most convenient to cover them here. Light Emitting Diodes (LEDs): The construction of an LED is similar to that of a laser diode, as indeed is …

Schottky Barrier Diode

Schottky Barrier Diode: Schottky junctions have been shown and described throughout this chapter, in conjunction with various devices that use them in their construction in Figure 12-4. Accordingly it will be realized that the Schottky Barrier Diode is an extension of the oldest semiconductor device of them all the point-contact diode. Here the metal-semiconductor interface …

Pin Diode Construction

Pin Diode Construction: The Pin Diode Construction consists of a narrow layer of p-type semiconductor separated from an equally narrow layer of n-type material by a somewhat thicker region of intrinsic material. The intrinsic layer is a lightly doped n-type semiconductor. The name of the diode is derived from the construction (p-intrinsic-n). Although gallium arsenide …
