Response to "Comment on 'Investigation of the optical and electronic properties of Ge2Sb2Te5 phase change material in its amorphous, cubic, and hexagonal phases'" [J. Appl. Phys. 97, 093509 (2005)]

Abstract

Upon review of experimental conditions, we conclude that the photoinduced current observed in thin film amorphous Ge2Sb2Te5 includes a dominant bolometric component under continuous illumination, while the spectrum recorded at a 30 Hz chopping frequency suggests a mixed photoconductive and bolometric response.
