WebIn this study, focused ion beam (FIB) machining was applied to fabricate Ge pillars with various diameters and crystallographic orientations from a few microns to sub-micron sizes. This provided specimens to be tested in the conventionally brittle temperature range of −100°C−400°C (0.14–0.56 T m ) to quantitatively study the effect of size on strength of Ge.
