Ultrasmooth Gold as a Top Metal Electrode for Molecular Electronic Devices

April 7, 2009
Author(s)
Mariona Coll Bau, Christina A. Hacker, Lauren H. Miller, Daniel R. Hines, E. C. Williams, Curt A. Richter
In the emerging area of molecular electronics, fabrication of reliable metallic contacts remains one of the most critical challenges. Nanotransfer printing (nTP) is an attractive low-cost non-destructive technique to provide contact to organic monolayers

Tracing Electronic Pathways in Molecules Using Inelastic Tunneling Spectroscopy

September 4, 2007
Author(s)
Alessandro Troisi, J M. Beebe, Laura B. Picraux, Roger D. van Zee, D R. Stewart, M Ratner, James G. Kushmerick
Using inelastic electron tunneling spectroscopy (IETS) to measure the vibronic structure of non-equilibrium molecular transport, aided by a quantitative interpretation scheme based on non-equilibrium Greens function/density functional theory methods, we

Building Electronic Function Into Nanoscale Molecular Architectures

August 30, 2007
Author(s)
H D. Abruna, M Ratner, Roger D. van Zee
The use of molecules in electronic circuit has been the subject of recent study. Experimentally, two-terminal, molecular rectifiers have been demonstrated, three-terminal, single-molecule transistors demonstrated, and electromechanical molecular switches

Energy-Level Alignment and Work Function Shifts for Thiol-Bound Monolayers of Conjugated Molecules Self-Assembled on Ag, Cu, Au, and Pt

July 1, 2007
Author(s)
Christopher D. Zangmeister, Laura B. Picraux, Roger D. van Zee, Yuxing Yao, J M. Tour
Photoemission spectra have been used to determine the energy-level alignment and work function of monolayers of 4,4'-bis-(phenylethynyl)benzenethiol, 2 naphthalene thiol, and 3-(naphthalen-2-yl)propane-1-thiol self-assembled on Ag, Cu, Au, and Pt. For each

Valence Electron Orbitals of an Oligo(p-phenylene-ethynylene)thiol on Gold

March 1, 2004
Author(s)
Christopher D. Zangmeister, Steven W. Robey, Roger D. van Zee, Yuxing Yao, J M. Tour
One- and two-photon photoemission spectra have been measured for monolayers of oligo(para-phenylene-ethynylene) thiolate chemisorbed on gold surfaces. Within 5 eV of the Fermi level, four states are observed, two occupied (2.0 eV and 4.0 eV below the Fermi
