Despite the considerable success of Eq. (7) in consistently rationalizing mobility data in many systems, the Gaussian Disorder Model misses the mark in one major way. The field-strength [E) dependence predicted for a realistic value of d (3.0, approximately the smallest a ever encountered in practice) and various values of E is shown in Figure 39 [63a,b]. Only for strong fields (sometimes only above 10 V cm ) are the results adequately described as linear functions of whereas experimentally this linearity usually extends to the lowest values of E accessible (sometimes as low as lO V cm ) [60b, 63c,d]. It was initially proposed that the...
