To demonstrate the controlled manipulation and redeposition of silicon surface atoms and clusters at room temperature using a scanning tunneling microscope.
Utilized a scanning tunneling microscope (STM) tip to apply combined electrostatic and chemical forces to strongly bound silicon surface atoms.
Controlled transfer forces and material removal by delivering voltage pulses across varying tip-surface separations at room temperature.
Achieved successful extraction of silicon atoms and clusters onto the STM tip followed by targeted redeposition at predetermined surface sites.
Demonstrated that the magnitude of transfer forces and quantity of displaced material are directly tunable via voltage pulse amplitude and tip separation distance.
