Abstract
Irradiation of obliquely deposited films of Se0.75Ge0.25 with 50-keV He+ ions produces enormous physical and optical densification. A thickness and hence volume contraction up to 39% accompanied by large changes (0.20 eV) in the band gap and refractive index (10.2%) have been observed. These changes are primarily due to the physical collapse of the low density columnar structure and associated electron-phonon coupling. Such large changes have great potential applications in high resolution image storage, holography, and lithography.
