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 dio...
Critically, device performance remains stable and highly repeatable after a multitude of temperature ramps to 475K. Capacitance-voltage measurements indicate widening the depletion region under increasing reverse bias voltage and a built-in voltage of 2.34V is recorded. The hBN p-type characteristic is...
When the PN junction is forward-biased as inFigure 3(b),the depletion region is narrowed and the potential barrier across it is lowered such that the majority carrier diffusion current increases. As the forward-biased diode voltage vDis increased the diffusion current Idincreases exponentially: \[...
2.PN Junction Characteristics– is another great article you must read to understand behavior of a PN junction under different conditions; say forward bias and reverse bias . This article will also help you understand why a PN junction is used in rectification applications. Now lets comes to the...
Forward and Reverse Bias If we connect the diode to a battery such that the battery’s voltage has the same polarity as the barrier voltage, the junction is reverse-biased. Diffusion current is further impeded because we are increasing the barrier voltage. Applying a reverse-bias voltage wide...
◆ Recombination and Generation in transition region 6. pn Junction Diode ◆ Recombination and Generation in transition region ※ Reverse-bias → Carrier concentration in the depletion region reduced → Causes the thermal generation of EHP : temperature, recombination center ※ Forward-bias → Carrier ...

The Vbi of a PN junction diode can be measured using a voltmeter. The diode is connected in reverse bias (negative terminal of the voltmeter to the P-layer and positive terminal to the N-layer) and the voltage across the diode is measured. This voltage is equal to the built-in potential...
If we consider the junction to be made up of material with Na acceptors per cubic centimeter on the p side and Nd donors on the n side, we can show that the contact potential is (Eq. 20)Vo=(kT/q)InNaNd/ni 2 Forward and Reverse Bias One of the useful features of a pn junction...
