STUDY OF BALANCE-EQUATIONS FOR HOT-ELECTRON TRANSPORT IN AN ARBITRARYENERGY-BAND .2.

In the present paper it is pointed out that the frictional forces and the energy transfer rate appear ing in the balance equations for the h ot-electron transport problem all depend explicitly on the electric fi eld. Their expressions are rederived with the electric field dependent corrections to O(E(1)) included. These expressions are identical with those of Lei-Ting except that in the latter the electron energy appea ring in the delta function and the distribution function are replaced by corresponding new-defined field dependent ones. The significance of such substitutions for obtaining the correct result is discussed in d etail.
