Ternary single-source precursors

A novel alternative approach is the use of ternary single-source precursors (SSPs), which have the I-III-VI2 stoichiometry built in and are suitable for low-temperature deposition (Fig. 6.3). Although a rich and diverse array of binary SSPs29-33 are known, characterized, reviewed, and tested, the number of known ternary SSPs is limited, as is their use in deposition processes.29 SSPs...

Our main discussion of the MOCVD preparation of III-V semiconductors is in Section III.A. Single-source precursors for III-V semiconductors have shown advantages and [Bu2 s.AlEt2]2 has been proposed by Cowley and coworkers as such a source. Other possibilities are available such as Et2A1 AsCHMe CHMe CHMe dHMe . Aluminium containing III-V semiconductors are often ternary phases. Cowley and coworkers have synthesized a potential ternary precursor containing an aluminium/arsenic moiety.
