## Description

- description: 'Optical atomic switches have garnered considerable interest due to
    its fast switching speed, low energy consumption, and compatibility with quantum
    information technologies. While atomic modulation via optical excitation has been
    demonstrated using scanning probe techniques, controlling atomic motion in operable
    devices remains a key challenge for practical applications. In this study, we
    operated an optical atomic switch and investigated molecular effects on conductance
    modulation. Single-molecule junctions incorporating C60, bipyridine, and butanediamine
    were fabricated using a mechanically controllable break junction technique. Photoirradiation
    induced conductance enhancement in all molecular junctions. Analysis of current–voltage
    characteristics in ON and OFF states revealed that atomic motion modulates the
    electronic coupling between the molecule and electrodes. A systematic comparison
    across different molecular junctions showed that molecular rigidity significantly
    influences optical conductance modulation, with flexible molecules like butanediamine
    exhibiting weaker dependence on initial conductance states.  '
