ELECTROLESS DEPOSITION OF SEMICONDUCTOR-FILMS

An electroless (solution growth) technique for the deposition of thin films of a variety of multicomponent alloys (e.g. Cd1-xZnxS, Pb1-xHgxS and Cd1-xPbxSe) of II-VI and IV-VI semiconductors has been developed. The technique involves the recombination on a suitably prepared substrate of two or more ions produced during a well-controlled chemical reaction. Films are obtained by an energetic ion-by-ion condensation process and exhibit nucleation and growth stages. The technique allows the preparation of thin films with polymorphic structures and variable compositions. © 1979.
