Nanowire formation in macroscopic metallic contacts: quantum mechanical conductance tapping a table top

摘要: In this letter we show that quantum mechanical conductance is observed in nanowires formed by placing two wires of macroscopic dimensions contact, making them vibrate so they get and out measuring the response such a system with an oscilloscope. We do tapping table top on which loose contact placed. The formation these associated quantized universal phenomenon occurs when any metals independently metal sizes. This should have strong technological implications studying formation, friction, tribology, forming breaking bonds, mechanics, etc., at nanoscopic level. Results simple specifications needed for are presented Au, Cu, Pt metallic glass wires.
