Calculate the approximate donor binding energy
Calculate the approximate donor binding energy for Si (r = 11.7,mxn= 1.18 m0)
Solution: From E= m*nq4 / 2(4 πε0εr)2 [h/(2 π)]2 we have
= 1.867 x 10-20 J = 0.117 eV.
Note: The effective mass used here is an average of the effective mass in different crystallographic directions, and is termed as the "conductivity effective mass" with values of 1.28 m0 (at 600 K), 1.18 m0 (at 300 K), 1.08 m0 (at 77 K), and 1.026 m0 (at 4.2 K).
