A diode is a two-terminal semiconductor device which allows electric current to flow in only one direction, and blocks the current flow in the reverse direction. Diode is normally made up of semiconductor materials like silicon or germanium. Based on construction and operation, there are several types of semiconductor diodes, but the most common type of semiconductor diode is the pn-junction diode. A pn-junction diode is formed by fusing a p-type semiconductor with an n-type semiconductor, where p-type semiconductor acts as the anode terminal and the n-type semiconductor acts as the cathode of the diode. When a forward voltage ... Read More

Introduction  Bipolar junction transistor is a semiconducting device. Silicon or Germanium are the two semiconductors used in Bipolar junction transistors. Three layers formed in between the two P-N junctions. They are named emitter, base, and collector. Emitter layer represented as E Collector layer represented as C Base layer represented as B The middle part of the transistor is known as Base layer (B). The base layer is the thin layer. The thickness of the base layer is 25 microns. The left side layer of the transistor is the Emitter layer (E). The right-side layer of the transistor ... Read More

An electric conductor is defined as a material that allows the flow of electric current or electric charges across it. In this article, we will discuss the differences between two important types of electric conductors: semiconductors and superconductors. What is a Semiconductor? Semiconductors are defined as a category of electric conductors whose conductivity ranges between that of insulators and conductors. Semiconductors are formed by mixing or doping impurity atoms with pure semiconductor elements. This addition of impurities enhances the conducting capabilities of the semiconductor material. Based on the type of element being doped, semiconductors are categorized into the following two ... Read More

Introduction Transistors, which are tiny electronic components, have two main uses. They can act as switches to control circuits and amplify signals. There is a rating for a particular voltage and current for each transistor. The three pins on modern transistors typically represent the emitter, base, and collector, respectively, of the transistor. The emitter, base, and collector are represented by these letters. Transistors of the anybody type on the left have a flat edge. The NPN and the PNP are the two primary types of bipolar transistors. Transistor Small electronic parts called transistors serve two main purposes. They can ... Read More

Introduction The semiconductor devices are known to display properties of partial electrical conductivity. They neither classify into mainstream conductors nor insulators and thus they permit partial conductivity in the process. These semiconductor diodes are further classified into two-terminal and threeterminal devices. Various forms of diodes fall under the category of two-terminal devices. The semiconductor diodes are also made of a single p-n junction and have metallic contacts on both the extreme ends to enable the application of external voltage into it. These diodes have the ability to conduct electricity in any one particular direction. What ... Read More
