Question

3. Use a computer program to plot the Fermi-Dirac distribution function Jo E) energy range 0-10eV. Assume that Ey 3.6 eV (a) Plot three curves on the same graph corresponding to the temperatures: 300K, 3000K, and 30000K Be sure to plot enough points. (b) Calculate d (c) Use a computer program to plot , over the energy range 0-10eV. Assume that E dE 3.6eV. Plot dE three curves on the same graph corresponding to the temperatures: 300K, 3000K, and 30000K. It is not possible to scale the graph so that all values are readily apparent, chose a scale that does the best job of conveying the information.

Explanation / Answer

MATLAB program to illustrate Fermi-Dirac distribution function set(0,'DefaultAxesFontSize',16,'DefaultAxesFontWeight','bold','DefaultAxesLineWidth',3); %% Fermi distribution function calculation kB = 8.617e-5; % in eV/K Ef = 3.6; % Fermi level in eV E = -0.2:0.0005:1.4; % Energy levels % "Calculate" f(E) at T=0 K as fTo fTo = zeros(size(E)); for k=1:length(E) if E(k)
