Mechanical deformation of InP and GaAs by spherical indentation

Bradby, J. E.; Williams, J. S.; Wong-Leung, Jennifer; Swain, M. V.; Munroe, P.


The mechanical deformation by spherical indentation of both crystalline InP and GaAs was characterized using cross-sectional transmission electron microscopy (XTEM) and atomic force microscopy. All load–unload curves show a discontinuity (or “pop in”) during loading. Slip bands oriented along {111} planes are visible in XTEM micrographs from residual indentations in both materials and no evidence of any phase transformations was found. Higher load indentations (35 mN for InP and 50 mN for GaAs)...[Show more]
