PN junction diode is symbolically represented as shown in picture. The direction of arrow is the direction of conventional current flow (under forward bias). Now lets try applying an external voltage to the pn junction diode.The process of applying an external voltage is called as “biasing”. ...
From these results combined with the results of Poisson equation analysis, we viewed the change in hole barrier as a function of applied voltage and obtained the value of the hole activation energy as ~0.06 eV in the p + -type layer around the flat-band voltage. We clarified the ...

The P-N Junction with Forward Bias Forward bias occurs when connecting the positive terminal of a battery to the P-type side and the negative terminal to the N-type side of the P-N junction – making the P-type side more positive than the N-type side. Figure 4 shows the reaction of...
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...
Where qe= 1.6 × 10−19C is the elementary charge, T is the material temperature (in K), and VT= kT/qeis thethermal voltage.At room temperature, VT≈ 25 mV. The net diode current under forward bias is: \[{{i}_{D}}={{I}_{d}}-{{I}_{0}}={{I}_{0}}({{e}^{{{v}...
Current transport mechanism of AlGaN/GaN Schottky barrier diode with fully recessed Schottky anode Both the forward and reverse-bias current transport mechanisms of an AlGaN/GaN Schottky barrier diode with a fully recessed Schottky anode (recessed-SBD) are investigated for the first time. A two-dime...
