The doping region
WebMar 2, 2024 · The depletion region is caused by the diffusion of charges. The holes and the electrons diffusing towards each other combine near the junction. In doing so positive and negative ions are formed. The pair of positive and negative ions at the junction forms the dipole. What causes the depletion layer? Why LED is highly doped? WebApr 10, 2024 · By adjusting the V doping content and the quantum dot size, the Fermi level difference between the CdTe and V-In 2 S 3 exhibits a monotonic and linear change, thus inducing a robust built-in ...

WebThe depletion region grows under reverse bias and shrinks under forward bias. It always extends mainly into the more lightly-doped side of the junction, due to the global charge neutrality requirement that NDxn = NAxp. The high level injection case is more complicated ( Guckel et al. 1982, Tiwari 1992, Warner and Grung 1983 ).
