ABSTRACT

There has been a clear emphasis, in the CD literature, on II-VI semiconductors, mostly CdS, some CdSe, and recently on ZnS. This being the case, the reader may reasonably expect this chapter to be a voluminous one. On the other hand, many of these studies have focused on deposition mechanisms and kinetics (which are dealt with in the previous chapter), with photovoltaic cells, and, to a lesser extent, with quantum size effects, both of which will be dealt with in subsequent chapters. Two detailed descriptions of the experimental procedure (for CdS and CdSe) are given in Chapter 2. This leaves the obvious question: “What’s left?” The present chapter will answer that question. This includes properties of the films not explicitly discussed in other sections, such as crystal structure, optical and electrical properties, as well as variants of the deposition process. Also, more detail will be given on non-Cd chalcogenides. In short, there is indeed much left.
