Depletion Region Width Solution

Follow our step by step solution on how to calculate Depletion Region Width?

FIRST Step Consider the formula

L d = L pn - L eff

Next Step Substitute values of Variables

∴

L d = 19mm - 8mm

Next Step Convert Units

∴

L d = 0.019m - 0.008m

Next Step Prepare to Evaluate

∴

L d = 0.019 - 0.008

Next Step Evaluate

∴

L d = 0.011m

LAST Step Convert to Output's Unit

∴

L d = 11mm
