Interplay between switching driven by the tunneling current andatomic force of a bistable four-atom Si quantum dot

Original language description

We assemble bistable silicon quantum dots consisting of four buckled atoms (Si4-QD) using atom manipulation. We demonstrate two competing atom switching mechanisms, downward switching induced by tunneling current of scanning tunneling microscopy (STM) and opposite upward switching induced by atomic force of atomic force microscopy (AFM). Simultaneous application of competing current and force allows us to tune switching direction continuously. Assembly of the few-atom Si-QDs and controlling their statesusing versatile combined AFM/STM will contribute to further miniaturization of nanodevices
