Filled and empty states of alkanethiol monolayer on Au (1 1 1): Fermi level asymmetry and implications for electron transport
Graphical abstract
Highlights
► Alkanethiol SAMs on Au are investigated via UPS and IPES measurements. ► The metal Fermi level is significantly closer to the LUMO than to their HOMO. ► The results suggest that charge carrier tunneling is controlled by the LUMO.

The origin of the transition voltage of gold-alkanedithiol-gold molecular junctions
2016, Chemical PhysicsCitation Excerpt :Therefore, we focus on the origin of these relatively lower Vtrans values in Au–C8DT–Au molecular junctions. The energy offset determined from Vtrans is much lower than the energy difference between the HOMO or LUMO of alkyl chains and the gold Fermi level [33]. We also notice that a filled state at ∼1.4 eV below the Fermi level of gold has been reproducibly observed in scanning tunneling spectroscopy of octanethiol molecules adsorbed on the Au(1 1 1) surface in the standing-up phase [61].
Self-assembled monolayer engineered interfaces: Energy level alignment tuning through chain length and end-group polarity
2015, Journal of Electron Spectroscopy and Related PhenomenaCitation Excerpt :One attractive method to tune the work function of a metal electrode is the use of surface modification through a self-assembled monolayer (SAM). SAMs are used in a wide variety of applications [7,8] and SAM-based engineering of electrode work functions in organic electronics is extensively studied and the mechanisms through which the SAM introduce an interface dipole is well understood [9–20]. A SAM interlayer does more than just modify the work function of a surface, it also separates the original surface from the organic semiconductor (OSC) overlayer.
