Abstract

Analysis of the experimental atomic radial distribution functions for thin amorphous films of zinc phosphides obtained by explosive laser sputtering has been performed within a fragmentary model. The experiment was carried out with an EMP-100A electron diffractometer in transmitted light at accelerating voltages of 50 and 75 kV. The films obtained by sputtering of β-ZnP2 single crystals contained nanoparticles of this phase. The films based on Zn3P2 turned out to be two-phase and consisted of dispersed Zn3P2 and β-ZnP2 nanoparticles. The composition of the film obtained on the basis of α-ZnP2 corresponded neither to any one of the known phases in the Zn-P system nor to any mixture of these phases. Crystallization of films in a divergent electron beam confirmed the results of the phase analysis performed using the model atomic radial distribution functions.
