Built-in voltage of pn junction formula
Did you know?
The p–n junction possesses a useful property for modern semiconductor 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. By manipulating this non-conductive layer, p–n junctions are commonly used as diodes: circuit elements that allow a flow of WebSummary: pn -Junction Diode Electrostatics A depletion region (in which nand pare each much smaller than the net dopantconcentration) is formed at the junction between p-and n-type regions A built-in potential barrier (voltage drop) exists across the depletion region, opposing carrier diffusion (due to a concentration gradient) across the junction:
WebBoth p and n junctions are doped at a 1e15/cm3 doping level, leading to built-in potential of ~0.59V. Observe the different Quasi Fermi levels for conduction band and valence band in n and p regions (red curves). A … WebA PN junction has Na=1019cm-3 and N d=10 16cm-3. The applied voltage is 0.6 V. Question: What are the minority carrier concentrations at the depletion-region edges? …
http://solarcellcentral.com/junction_page.html WebIn a p/n junction, an equilibrium condition is reached in which a voltage difference is formed across the junction. This voltage difference is called the "built-in electric field", or "built-in voltage". Electrons near the p/n interface tend to diffuse into the p- region. As electrons diffuse, they leave positively charged holes in the n- region.
WebAug 17, 2016 · p p = N A − N D with Na and Nd being the acceptor / donor doping in the p-region Assuming you know algebra you can easily express the built in voltage in terms of the acceptor and donor concentrations.
