PREPARATION AND RELATIVE MECHANICAL STRENGTH OF ERBIUM MONOSELENIDE FILMS

Abstract

For the first time was developed the technology of preparation of thin crystal films ErSe by method of vacuumthermal evaporation from two independent sources of components and pre-synthesized ErSe volume material. The relative mechanical strength of the prepared films is studied by method of the complete attrition. It is shown that the relative mechanical strength of films depends on the method of preparation. Films prepared with method of discrete evaporation have considerably (30-35%) high mechanical strength, than films prepared with evaporation from two independent sources. It is possible, that it is connected to the fact that the crystalline structure of the films prepared with discrate evaporation is more perfect.
