Temperature-dependent molecular conduction measured by the electrochemical deposition of a platinum electrode in a lateral configuration

摘要

Temperature-dependent current-voltage (I-V) characteristics of a molecule, 1,4-benzenedimethanethiol, was measured for 30 K100 K is typically 0.11 eV. For T<40 K, the observed temperature independent I-V characteristics are fitted to the Fowler-Nordheim tunneling expression with barrier height of 1-2 eV depending on the contact strength of samples.
