The space charge region on the two junction sides is referred to as the depletion region/transition region due to the lack of free charge carriers in the region. Depletion width is the sum of depletion region boundaries on the p-region side and n-region side. The region outside the depleti...
This space near the junction carrying those positive and negative charges is known as depletion region or depletion layer.Hence, the diffusion of holes and electrons in N-type region and P-type regions to neutralize the both regions of the PN junction is the cause of depletion region formation...

Simultaneous conductance imaging and constant current mode STM imaging have been used to delineate Si pn junction arrays over a range of revrse bias conditions.Conductance has been obtained by adding a modulation signal to voltages applied in the p and n regions of a model device,and by ...
On the other hand, the pn configuration has higher optical loss when compared to junctions that have an intrinsic region, since its active area is fully doped with charge carriers. For depletion modulators, due to the diode behaviour of the junction, the depletion saturates for high voltages [...
A metal:p‐n‐CdTe Schottky‐barrier solar cell: Photoelectrochemical generation of a shallow p‐type region in n‐CdTe A simple method for producing a Au:p‐n‐CdTe Schottky barrier is described. The shallowp‐njunction is formed by photoelectrochemical surface oxidization ... JR Pugh,D Mao...
where εs is the electrical permittivity of silicon, q is the charge of an electron, φi is the “built-in” potential of the pn junction, NA and NB are the doping concentrations of p-region 101 and n-region 102, respectively. As shown in FIG. 1, the horizontal axis shows the vol...
Dopant-induced random telegraph signal in nanoscale lateral silicon pn diodes at low temperatures. Kelvin probe force microscope, RTS is ascribed to trapping/detrapping of carriers by/from a single dopant near the farther edge of the depletion region... Purwiyanti,Sri,Nowak,... - 《Applied Phy...
Insulated gate field-effect transistorsare unipolar devices just like JFETs: that is, the controlled current does not have to cross aPN junction. There is a PN junction inside the transistor, but its only purpose is to provide that nonconducting depletion region which is used to restrict current...
