In this letter, we demonstrate rapid decomposition in Ge-doped SiO[sub 2] glass under high-energy electron irradiation, and comment on possible mechanisms for the interaction of the electron-beam with the glass. Nanometer-scale modifications in Ge-doped SiO[sub 2] glasses can be obtained by the redistribution of Ge in the glasses as a result of patterned electron-beam writing.
