Abstract
The nanostructured Ge and Si processed by severe plastic deformation (SPD) has been studied by various techniques. TEM, XRD, Raman scattering and phot oluminescence measurements. The as-prepared samples are characterized by bo th a small grain size and a specific defect structure of grain boundaries ( GB). Microstructural aspects of optical properties in nanostructured Ge and Si are discussed. (C) 1999 Acta Metallurgica Inc.
