Organometallic growth of II–VI compounds

Developments in the organometallic growth of II–VI compounds are reviewed with an emphasis on epitaxial growth related problems. The advantages and disadvantages of organometallic growth are compared with analogous growth using conventional VPE techniques. Consideration is given to the growth of specific compounds using alkyls of Zn, Cd or Hg with the elements O, S, Se and Te as hydrides or alkyls. Special reference is given to the decomposition characteristics of typical alkyls such as ( C 2 H 5) 2 Te, ( CH 3) 2 Te and ( CH 3) 2 Cd by pyrolysis in H 2. Reaction mechanisms involving homogeneous and heterogeneous pyrolysis, adduct formation and the potential role of adsorption on parameters such as growth rate are discussed.
