Investigating Nanopillars: Silicon Brittle? Not This Kind! Oct 14, 2009
"Our pillar-bending tests are in principle the same as Tetmajer s experiments, only our pillars are about a hundred thousand times smaller,? says Michler. To apply a force to the columns the scientists used a micro- and nano precision tool called a nanoindenter, where the flattened tip of a pyramid-shaped diamond tool, mounted in a scanning electron microscope, presses down along the longitudinal axis of a silicon column. The force exerted by the tip is continuously measured. Larger? pillars... (Science Daily)
