Consider two pn silicon junctions at T $300$ K reverse biased at VR $5$ V$.$ The

impurity doping concentrations in junction A are N a $1018$ cm$3$ and Nd $1015$ cm$3$

$,$

and those in junction B are Na $1018$ cm$3$ and Nd $1016$ cm$3.$ Calculate the ratio of

the following parameters for junction A to junction B: $($a$)$ W$,($b$)$ Emax $,$ and $($c$)$ Cj
