Question

interpolation by MATLAB's interpl function. The mobility of electrons, , in silicon is dependent on temperature. T and is often presented as a table of laboratory measurements for a few distinct temperatures [2]. If we wish to determine the electron mobility at a tempera ture that is not in the table, we need to interpolate. Table values for electron E3.6 mobility, Mu (em/V-), at temperatures, 'T (K), are specified in the vecon Mut and Tt, respectively temperatures, T (K), are specified in the vectors Tt = [100 150 200 250 300 350 400 4501 Mut = [19650 7427 3723 2180 1407 972 705.5 531.8); We wish to determine Mu at temperatures T2 where T2 = [130 425 280 335] Create a MATLAB program that evaluates Mu at temperatures T2 using MATLAB's interpl function. a. Print the results to a file in table format. b. Create a plot of Mu vs. T
