Abstract

IR analysis shown the ratio between different CH hybridization bonds sp1:sp2:sp3 1O:O. 09:O. 81 in a-C:H layer of a-C:H/a-Se and 0:0:1 of a-C:H/KC1. The ratio between the sp3-type configurations is sp3CH:sp3CH:sp3 CH3 0. 28:0. 38:0. 34 in a-C:H/a-Se and 0. 45:0. 33:0. 22 in a-C:H/KC1. A model of the non-equilibrium crystaflization of the layer in both films is proposed. Computer simulated figures are fractals with the dimension D1 1. 37 0. 02 in a-C:H/a-Se and D2 1. 81 in a-C:H/KC1. In good agreement with the experimental data D1 1. 35 0. 04 and D2 1. 77 0. 03.
