The centimeter range one-and two-dimensional nanostructures of 70nm pitch have been imprinted by hot pressing with a quartz, silicon or nickel mold, at 240 degrees C, onto the surface of Ge20As20Se14Te46 semiconductor glass. Excellent glass stability of this glass allows multiple re-pressing of the nano-structures. With increasing the Te/Se ratio in the glass formula, the refractive index reaches a value of 3.5 with an option of free electron absorption at elevated temperatures pointing out the use of such nanostructures in submicron and micron scale electronic devices/chips, moth eye structures and photonic crystals.
