Mention the order of electric field in the depletion region in an unbiased junction diode.

Explanation

For a thickness of one micron and for a silicon diode of voltage 0.7V, electric field will be
`(0.7)/(10^(-6)) = 0.7 xx 10^(-6) Vm^(-1) ~~ 1.0 xx 10^(6) Vm^(-1)`.
Hence the order of the field in the depletion region is `10^(6)Vm^(-1)`.
