Step of 5 3.011P The Einstein relationship to calculate diffusion constant for electrons and holes is, D, = = = 26 Here, n represents mobility of electrons D represents diffusion constant for electrons VT represents thermal voltage at room temperature represents mobility of holes represents diffusion constant for holes Case(i): Substitute 1350 for 26 mV for VT v) = 35.1 Step of 5 Case(ii): Substitute 1200 cm²/V.s for and 26 mV for VT. = = 31.2 cm2 Case(iii): Substitute 750 for and 26 mV for VT. = Step of 5 Case(iv): Substitute 380 for and 26 mV for VT. = = 9.88 Step of 5 The diffusion constant for holes, Case(i): Substitute 480 for and 26 mV for VT. Case(ii): Substitute 400 for and 26 mV for VT. = = 10.4 Step of 5 Case(iii): Substitute 260 for and 26 mV for VT. Case(iv): Substitute 160 for and 26 mV for VT. Therefore, the diffusion constant for electrons for the four cases are, 35.1 /s,31.2 cm2 /s,19.5 cm2 /s,9.88 The diffusion constant for holes for the four cases are, 12.48 /s,10.4 cm2 /s,6.7 cm2 /s,4.16 cm2 /s
