This invention discloses an atomic-level construction method for a fixed-axis molecular rotor and its array on a semiconductor substrate. Metal atoms and phthalocyanine molecules are deposited on the semiconductor substrate surface using an ultra-high vacuum thermal evaporation method. The phthalocyanine molecules are laterally manipulated using a scanning tunneling microscope (STM) to place them onto the surface-adsorbed metal atoms. The metal atoms are then longitudinally manipulated using the STM to place them onto the phthalocyanine molecules, resulting in a metal atom-phthalocyanine molecule-metal atom fixed-axis molecular rotor composite structure. The rotation and control of the molecular rotor are achieved by applying a gate voltage to regulate the local potential. This method achieves atomic-level precise anchoring of the molecular rotor composite structure and realizes the rotor array arrangement. The rotation speed is controlled by regulating the local potential through the gate voltage of pre-embedded electrodes. By precisely designing the molecular rotor array using individual atoms and molecules as basic units, the problem of the inability to reposition and arrange molecular structures is solved.
