selected for the overwhelming majority of them. But, in fact, silicon is a rather poor semiconductor if judged on its physical properties alone, comparing unfavorably with germanium and gallium arsenide, as shown in Table 1.

Natalia P. Bechtereva,Diliara K. Kambaroval work has been devoted to this subject that its collection has already provided material for several review articles and two books have been entirely devoted to it: one, by Boltaks, in 1961 , the other, by Sharma, in 1970 . Since the latter gives excellent coverage of the literature until 196

Nevertheless semiconducting properties can be found in noncrystalline media, and it is also possible that useful devices can be produced which would not be available from the conventional materials.

Individual and Small Group Decisionsorigins in the nonlinearity of these equations. However, it is only in the past decade that nonlinear . phenomena have been demonstrated and exploited. The first measurement of this kind was the (now classic) experiment of Franken, Hill, Peters, and Weinreich in which ultraviolet light (at λ = 3
