A p-n step junction diode is made out of Rossonium. Rossonium is a semiconductor remarkably like silicon only it has a relative permittivity of 11.7 and a band gap of Eg = 1.15eV. Your device has NA = 3.00E + 16 cm-3 and ND = 3.00E + 16cm-3. Assume that the device is in equilibrium at T = 290K and the minority carrier lifetimes are tau = 1mu s and the effective masses are mn* = 1.15m and mp* = 0.60m, where m is the free electron mass. Account for the appropriate temperature dependencies. Calculate xn, xp, W, Vbi, epsilon max, ni, NV, and Nc using conventional units (cm, volts, etc.) and show the results in a neat manner using scientific notation and two decimal places. The work should be shown on a separate page while the answers are recorded here using scientific notation to 2 decimal places where it is appropriate. Use the depletion approximation and assume that the p-side of the device is grounded to find: the space charge density, rho(x), the electric field, epsilon (x), and the voltage, V(x). Use the geometry shown above with the p-side on the left and the pn junction located at x = 0. The idea here is to write down the mathematical functions themselves using appropriate numerical values. Use Excel, Matlab (or whatever) to accurately plot an energy band diagram for this diode. Use the parameters and geometry shown above. The band diagram should include Ec(x), Ei(x), EF(x), and Ev(x) all on the same plot. The width of the plot should be about 4W and you should plot 51 points. Again, accurately plot epsilon (x) for this diode using the parameters, geometry and horizontal scale shown above. Again, accurately plot n(x) and p(x) for this diode using the parameters and geometry shown above. Use a semi-logarithmic graph i.e. a log scale for the y-axis (n and p) and the same linear scale as above for the x-axis.Explanation / Answer
