## Description

- description: The effect of 3,4,9,10-perylene-tetracarboxylic-dianhydride (PTCDA)
    adsorption to the physical properties of a two-dimensional (2D) atomic-layer superconductor
    (ALS) In/Si(111)-(√7×√3) has been studied by angle-resolved photoelectron spectroscopy,
    transport measurements and scanning tunneling microscopy. Hole doping from the
    adsorbed molecules has been reported to increase the Tc of this ALS, and the molecular
    spin to decrease it. Owing to its large electron affinity and its nonexistent
    spin state, the adsorption of PTCDA was expected to increase the Tc. However,
    the PTCDA adsorption dopes only a small amount of holes and causes a suppression
    in Tc with a sharp increase in the normal-state sheet resistance, followed by
    an insulating transition. Taking disordering of the arrangement of PTCDA into
    account, we conclude that the increase in conductivity results from the localization
    effect resulting from the random potential that is induced by the disordered PTCDA
    molecules. The present result also indicates the importance of the crystallinity
    of 2D molecular film adsorbed on ALSs.
