1)A thick slab of p-type Si (many times thicker than the diffusion length Ln ) with 0.52 cm bulk resistivity is illuminated. For a uniform generation profile in the slab of 10 19 electron-hole pairs/(cm 3 s), if the minority carrier lifetime is 500 s, and the surface recombination velocity is 200 cm/s, calculate the … Read more

Matlab

MATLAB Project 1 1. In this problem, you will use MATLAB to generate and plot the discrete-time signal [n] and unit step function u[n]. MATLAB provides two built-in functions that will be useful. The call zeros(m,n) returns an array of zeros with m rows and n columns. Similarly, ones(m,n) returns an m narray of ones.  … Read more
