1. Write a Matlab program to confirm that the ni versus T curve for Ge and Si graphed in Figure 2.20 can be generated by employing the empirical fit relationships below. Check over the temperature range of 275K ≤ T ≤ 375K. ni(Si) = (9.15x10^19)[(T/300)^2]x e^-0.5928/kt ni(Ge) = (1.76x10^16)[(T)^3/2]x e^-0.392/kt 2. Generate a MATLAB program to compute and plot the Fermi function, f(E), and 1- f(E) versus ΔE = E-Ef for values of ΔE that is over the range of -0.5eV ≤ ΔE ≤ 0.5eV for varying temperature settings where Temperature = 150, 250, 350, 450 and 550K. Make sure that each f(E) versus ΔE curve at each temperature is superimposed on the same plot. Discuss what you see in your plots as the Fermi function, f(E), and 1-f(E) varies with temperature and energy. 3. Consider GaAs at T = 300K with Nd =0. (a) Plot the position of the Fermi energy level with respect to the intrinsic Fermi energy level as a function of the acceptor impurity concentration over the range of 1014 ≤ Na ≤ 1017 cm-3. (b) Plot the position of the Fermi energy level with respect to the valence-band energy over the same acceptor impurity concentration given in part (a). The temperature of a sample of GaAs is T = 300K and the acceptor doping concentration is Na = 0. Plot the minority carrier concentration (on a log-log plot) versus Nd over the range 1015 ≤ Nd ≤ 1018 cm-3
what are the different methods used in frequency response analysis
Give the truth table and the logical expression for a circuit with three inputs and one output. The output generates even parity for inputs. Use EXOR/EXNOR in the output expression when possible.
Design an LC circuit to protect the tungsten filament of an ordinary 75-Watt incandescent light bulb from over the current-transients greater than 50% of the normal operating current at the moment of turn-on
similarly, let y=y0y1 represent another number with the same four possible values. the output f should be 1 if the numbers represented by x and y are equal.otherwise, f should be 0. A- show the truth table for f B- synthesize the simplest possible ..
Store the arrival times in memory locations starting from $1000.(Do this is in C. Store the results in an array and don't worry about the speci c location of the results.)
