## Description

- description: Molecular electronics is attracting increasing attention due to its
    potential application in post-silicon electronics. However, fabrication of molecular
    junctions, the fundamental building block of molecular electronic devices, requires
    complicated procedures, which hamper the efficient development of novel devices.
    Here, we propose a simple fabrication process by utilizing an atomic switch operated
    by redox reaction and migration of metal atoms. The Ta2O5-based silver atomic
    switches were operated with a small operation voltage (0.3 V) in an acetylene
    atmosphere under an ultra-high vacuum. The consecutive operation of the atomic
    switch shows novel conductive states around 0.1 G0 (G0 = 2e2/h). Inelastic electron
    tunneling spectra and first-principles calculations reveal that the observed conductive
    states are attributed to the acetylene molecular junctions on the silver filament.
    The proposed method accelerates the development of devices through the marriage
    of molecular junctions with atomic conductive filaments.
