In-situ Observation of Shear Deformation of Gold Single Real Contact Point at the Nanoscale

We in-situ observed the deformation of a gold single real contact point at the nanoscale during friction experiment in order to reveal the mechanism of friction. In this experiment, a special experimental setup combining between micro-electro-mechanical system (MEMS) and transmission electron micros...
