Linearly graded junction 意味

NettetA detailed analysis of the depletion layer of exponentially graded p-n junctions is presented, which improves previous efforts in this field in different aspects. (1) We obtain analytical expressions for the depletion layer widths which are nearly as simple as those given by the widely used step and linearly graded junction models, but by far more … NettetA certain PN junction has a linearly graded junction on the p-side, Na = ax, where x is the distance from the physical junction to p-side and a = 1019 cm-4 , and a uniform doping of 3 x 1014 cm-3 on the n-side. It is operated at T=300K. A. Calculate the electric field as a function of x? B.

The effect of the radius of curvature of the metallurgical junction (or junction curvature) on avalanche breakdown voltage is herein computed numerically for spherical and cylindrical p- n junctions in Ge, Si, GaAs and GaP. Three types of impurity distribution have been considered: abrupt, linearly graded and composite.

Nettet19. feb. 2014 · Abstract. In this work, we present a new model to derive charge and capacitance–voltage (C–V) characteristics for linearly graded p–n junction under reverse polarization using pseudo-equilibrium approach. Furthermore, we propose a compact C–V model under any polarization for this junction type.
