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).
A circular ring of magnetic material has a mean length of 1m and a cross sectional area of .001m^2.A sawcut of 5mm width is made in the ring . calculate the magnetizing current req
Consider the 220-V, 1800-r/min dc motor, controlled by a three-phase fully controlled rectifier from a 60-Hz ac source. The armature-circuit resistance and inductance are 1.5 and
