Q2.
N_(A)(x)=10^(14)+10^(18)e^(-10^(4)x)
, where
x
is measured in
cm
.\
j_(n)=q\\\\mu _(n)n(E+V_(T)(1)/(n)(deln)/(delx)), and ,j_(p)^(T)=q\\\\mu _(p)p(E-V_(T)(1)/(p)(delp)/(delx))
\ i. Using the relevant equation from the equations mentioned above, demonstrate that the material must have a nonzero internal electric field
E
.\ ii. What is the value of
E
at
x=0
and
x=5\\\\mu m
?\ (Hint: In thermal equilibrium, the total electron and total hole currents must each be zero.)
