We demonstrate the feasibility of building an abacus on the nanometer scale using single molecules as “counters”, Cu monoatomic steps as “rods” that constrain the molecular motion to one dimension, and the scanning tunneling microscope as an “actuator” for counting operations 关键词: copper;fullerenes;nanotechnology;scanning tunnelling microscopy;room-temperature repositioning;individual C60 molecules;Cu steps;molecular counting device;room temperature;scanning tunneling microscope;step direction;abacus;nanometer scale;molecular motion;actuator;counting operations;Cu;C60
