Precursor single-molecule

Later on, this concept was extended to precursors containing both elements of the desired material already connected by a chemical bond in a single molecule. Such precursors are mainly referred to as single source precursors. Their potential application for the deposition of thin films of the corresponding binary materials by MOCVD processes could be demonstrated. In particular Lewis acid-base adducts R3M—ER3 and four- and six-membered heterocycles [R2MER x (Fig- 1) have been in the focus of research groups both in industry and university. Consequently, the development of powerful synthetic pathways for the preparation of such precursors has been forced. [Pg.120]

In attempts to reduce toxic hazards, eliminate homogeneous prereactions, lower deposition temperatures, and use cheaper precursors there have been considerable efforts directed toward the development of alternative precursors for use in MOCVD.10 Another approach to using intrinsically less reactive compounds is to use a single-molecule (or single-source ) precursor, in which all the elements required in the film are present in the one molecular species. The compounds potentially exhibit many or all of the following advantages over conventional MOCVD precursors ... [Pg.1029]

One of the potential strategies for the synthesis of compound semiconductors is the pyrolysis of a single-molecule precursor that incorporates the elements of a compound into a single molecule. For a number of binary materials, predominantly metal oxides but also compound semiconductors, such as GaAs [101] or metal alloys [102-104], it has been demonstrated that the use of single-molecule precursors (SMPs), which contain both components for the respective material in one molecule rather than applying two independent... [Pg.60]
