Intrinsic
Electron Conduction Mechanisms in Molecules

Electron devices
containing molecules as the active region have been an active area of research
over the last few years. This talk
presents measurements in a variety of molecular systems to elucidate the
transport mechanisms, specifically in self-assembled monolayers (SAMs) using
nanometer scale devices. Detailed kinetic studies are necessary to distinguish
between different conduction mechanisms; for example, in alkanes
temperature-independent electron transport is observed, proving tunneling as
the dominant conduction mechanism when defects are eliminated from the device
structure. This is distinct from
Langmuir-Blodgett films, where only defect or filamentary conduction has been
observed. From the bias-dependence of b, a barrier height FB of 1.39 ± 0.01 eV and a zero field decay coefficient b0 of 0.79 ± 0.01 Å-1 are determined for alkanethiols. Inelastic
electron tunneling spectroscopy of the molecules in the junction exhibits
well-defined modes of the molecules in the junction, and yield a measurement of
the intrinsic linewidths of these modes. Deviation from this classic behavior for more complex molecule
structures, and a comparison of the differences and pitfalls of various
fabrication and characterization approaches, will be discussed.
