Question2: A pn junction uses NA = 2x1016 /cm and Np-9x1015 /cm?. Determine the built-in voltage at room temperature (T-600k)? Question3: Find the built-in voltage in a pn junction with acceptor concentration=101/cm and donor concentration=1015/cm³. Also, calculate the width of the depletion region and the magnitude stored on each side of the junction. Use n-1.5x1010 Icm', &, = 11.7 8o, Eo-8.854x1014 F/cm, q=1.6x10-19c Question4: A pn junction is biased with a reverse voltage (VR) and is doped with NA = 2x1016 Icm and ND-8x1015 /cm Determine the capacitance of the device with (a) VR-0v; (b) VR=1v. E, = 11.7 Ep, Eo-8.854x10-14 F/cm, q=1.6x10-1°c, n=1.5x1010 /cm³ , m=1/3, Vr=25.8mV, Cross- section area = 2x10-cm?.
