10) The thickness
of depletion region is of the order of one-tenth of a
micrometre Due to the positive space-charge region on
n-side of the junction and negative space charge region
on p-side of the junction, an electric field directed from
positive charge towards negative charge develops Due
to this field, an electron on p-side of the junction moves
to n-side and a hole on n-side of the junction moves to p-
side
