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)

摘要

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.
