For a parabolic graded junction with doping gradient profile as shown in figure. At no bias, draw the shape of space charge distribution, the electric field and the potential distribution around the junction, henc show that the total depletion width is given by the relation: \[ W=\sqrt[4]{\frac{24 \varepsilon V_{d}}{q}} \]
