PN junction Diode plays a vital role in our electronic fields, because of their unique property (current flows in only one direction) they are used in many electronic or electrical circuits like rectifiers, switches, clippers, clampers, voltage multipliers. PN junction diode is one of the fundamental elements in electronics. In this type of diode, we dope one side of a semiconductor piece with an acceptor impurity and another side with a donor impurity.

when a semiconductor is doped with p-type and n-type impurities, a pn junction is formed which acts as a diode and prevents the charge carriers to flow to either side of junction Semiconductor PN Junction Diode is the simplest semiconductor device. One terminal of p-n junction diode is Anode and other is cathode. Depletion region created across the pn junction by the initial movement of majority carrier across the junction. Depletion layer opposes only the the majority carrier not minority carrier.
Pn junction diode characteristics: P-n junction diode shows zero resistance in the forward direction and infinite resistance in the reverse direction. i.e., it is not a perfect diode. Before using this diode, it is necessary to know a little about its characteristics and properties with forward bias and reverse bias. Forward biasing a PN Junction diode . Image Source Forward biasing a pn junction diode is very simple. You just need to take a battery whose values can be varied from (o to V volts), connect its positive terminal to the p-side of pn junction diode and then connect the negative terminal of battery to the n-side of the pn junction diode. If you
The p–n junction possesses essential properties for modern electronics. A p-doped semiconductor is relatively conductive. The same is true of an n-doped semiconductor, but the junction between them can become depleted of charge carriers, and hence non-conductive, depending on the relative voltages of the two semiconductor regions. Description. In this video tutorial, we will learn all the basic concepts related to Semiconductors. Starting from the basics such as P-N Junction diodes and their biasing, we will progress to discuss topics such as Photo diodes, Zener diodes, and the use of semiconductors as rectifiers.
Summary: pn -Junction Diode I-V Under forward bias, the potential barrier is reduced, so that carriers flow (by diffusion) across the junction Current increases exponentially with increasing forward bias The carriers become minority carriers once they cross the junction; as they diffuse in … an abrupt p-n junction. Frequently we will deal with p-n junctions in which one side is distinctly higher-doped than the other. We will find that in such a case only the low-doped region needs to be considered, since it primarily determines the device characteristics. We will refer to such a structure as a one-sided abrupt p-n junction.
PN Junction Diode. If a suitable positive voltage (forward bias) is applied between the two ends of the PN junction, it can supply free electrons and holes with the extra energy they require to cross the junction as the width of the depletion layer around the PN junction is decreased. A p-n junction diode allows electric current when it is forward biased and blocks electric current when it is reverse biased. This action of p-n junction diode enables us to …
PN Junction Theory A PN-junction is formed when an N-type material is fused together with a P-type material creating a semiconductor diode In the previous tutorial we saw how to make an N-type semiconductor material by doping a silicon atom with small amounts of Antimony and also how to make a P-type semiconductor material by doping another silicon atom with Boron. The difference between forward bias and reverse bias is that in forward biasing positive terminal of the battery is connected with the p-type and negative terminal is connected with n-type of semiconductor, while in reverse biasing positive terminal of the battery is connected with the n-type and negative terminal is connected with p-type.
What Is a PN Junction When a p-type semiconductor is suitably joined to an n-type semiconductor, the contact surface is called pn junction. Most semiconductor devices contains one or more pn junctions. The pn junction is of great importance as it is the main control element for the semiconductor devices. Formation of pn Junction In actual PN junction diode is one of the fundamental elements in electronics.

PN junction diode is a two terminal device, the characteristics of diode depends on the polarity of the external potential applied to the PN junction diode. The junction of N and P semiconductors is free of charge carriers; hence the region is called as depletion region. Fig.1. P-N Junction Diode Junction Diode Symbol and Static I-V Characteristics: Fig.2. V-I Characteristics of p-n junction. There are two operating regions and three possible “biasing” conditions for the standard Junction Diode and these are: 1. Zero Bias – No external voltage potential is applied to the PN junction …
