Semiconductor Physics and Device, D$.$ A$.$ Neamen, $3$rd edition Let $$p$0=10-7$ s and $$n$0=5\backslash$times

$10-7$ s$.$ Also let n$=$ p$=$ ni $=1010$ cm$-3.$ Assume very low injection so that $$n

$<<$ ni$.$ Calculate R$/$n for a semiconductor which is $($a$)$ n$-$type $($n$0>>$ p$0)$; $($b$)$

intrinsic $($n$0=$ p$0=$ ni$)$; $($c$)$ p$-$type $($p$0>>$ n$0)$
