AbstractThis paper first briefly reviews a few of the early studies that established some of the salient features of light-induced degradation in a-Si,Ge:H. In particular, I discuss the fact that both Si and Ge metastable dangling bonds are involved. I then review some of the recent studies carried out by members of my laboratory concerning the details of degradation in the low Ge fraction alloys utilizing the modulated photocurrent method to monitor the individual changes in the Si and Ge deep defects. By relating the metastable creation and annealing behavior of these two types of defects, new insights into the fundamental properties of metastable defects have been obtained for amorphous silicon materials in general. I will conclude with a brief discussion of the microscopic mechanisms that may be responsible.

Necessary And Sufficient

In this paper, we introduce the notion of semi-invariant submanifolds of a normal almost paracontact manifold. We study their fundamental properties and the particular cases. The necessary and sufficient conditions are given for a submanifold to be invariant or anti-invariant. Also, we give some results for semi-invariant submanifolds of a normal almost paracontact manifold with constant c and we construct an example.

Some philosophers regard no reducible physical properties as perfectly natural. However, in scientific practice, some but not other reducible physical properties (such as the property of having a given center of mass) denote genuine, explanatorily potent respects in which various systems are alike. What distinguishes these natural reducible physical properties from arbitrary algebraic combinations of more fundamental properties? Some philosophers treat naturalness as a metaphysical primitive. However, this chapter I suggests that it is not—at least, not as far as the naturalness of reducible physical properties is concerned. Roughly speaking, it is argued here that a reducible physical property’s naturalness is grounded in its role in the explanation of laws.
