In the case of forward biasing of pn junction
WebA silicon diode has a voltage drop of approximately 0.7V, while a germanium diode has a voltage drop of approximately 0.3V. Though germanium diodes are better in the area of forward voltage drop, silicon diodes are cheaper to produce and have higher breakdown voltages and current capabilities. Credits: Google. Comment. WebFeb 24, 2012 · The PN junction is said to be in reverse biased condition. When there is no voltage applied across the p n junction, the potential developed across the junction is 0.3 volts at 25 o C for germanium on the junction and 0.7 volts at 25 o C for silicon p n … We use semiconductor materials (Si, Ge) to form variety of electronic devices.

WebWhen a p-n junction diode is forward biased, i.e. forward biasing voltage V is applied to the diode, this potential difference reduces the barrier potential V o .The effective barrier … Web2 Biasing of the pn Junction First, it is worth describing the physical mechanism qualitatively of a diode under di erent biasing conditions, as shown in Figure 2. In the zero bias case, the di usion currents are equal and opposite to the drift currents giving rise to zero current ow across the pnjunction. The internal electric eld generated
WebWhere is forward biasing used? Forward bias or biasing is where the external voltage is delivered across the P-N junction diode. In a forward bias setup, the P-side of the diode is attached to the positive terminal and N-side is fixed to the negative side of the battery. Here, the applied voltage is opposite to the junction barrier potential.
