Abstract
Acoustic emission activity vs. electrical field has been studied in thin Ge Se films applying electrical field up to 10(9) V/m. On the base of the obta ined results the mechanism of the breakdowns has been determined. Structura l changes in the thin films have been investigated. Transformation of struc ture from amorphous to polycrystalline state has been observed. (C) 1999 El sevier Science B.V. All rights reserved.
