Position control at the nanoscale can be achieved through various techniques, including:
Atomic Force Microscopy (AFM): This technique uses a sharp tip to manipulate atoms and molecules with high precision. Scanning Tunneling Microscopy (STM): STM allows for the precise positioning of individual atoms by using a tunneling current. Electron Beam Lithography (EBL): EBL is used to create patterns at the nanoscale by focusing an electron beam on a surface. Optical Tweezers: These use laser beams to trap and move nanoscale particles with high accuracy.
