[Audio] Molecular Conduction Workshop 2007
This is the 5th in a series of annual workshops on Molecular Conduction – the prior workshops have been in W. Lafayette (2003, 2005), Evanston (2004) and Virginia (2006). The workshop has been an informal and open venue for discussing new results and key challenges. Two years ago, we expanded the theme of the workshop to include molecular-scale sensing, i.e. nano-scale sensor elements for chemical and biological sensing.

MCW07 Exploring Trends in Conductance for Well-Defined Single Molecule Circuits
In our recent research, we have been able to measure and characterize the impact of intrinsic molecular properties on the conductance of single molecule circuits formed with amine-gold linkages. In this talk, I will review the experiments and the physical picture of the junction based on the...

MCW07 Metal-Molecule Interface Reactions for Silicon-Based Molecular Electronic Devices
The interaction of deposited metals with monolayer films is critical to the emerging arena of molecular electronics. We present the results of a thorough study of the interaction of vapor-deposited Au and Ag on alkane films attached to Si substrates.

MCW07 A Quantum Open Systems Approach to Molecular-Scale Devices
Experimental advances in electrically and optically probing individual molecules have provided new insights into the behavior of single quantum objects and their interaction with the nanoenvironments without requiring ensemble average. Molecular-scale devices are open quantum systems whose…

MCW07 Physics of Contact Induced Current Asymmetry in Transport Through Molecules
We first outline the qualitatively different physics involved in the charging-induced current asymmetries in molecular conductors operating in the strongly coupled (weakly interacting) self-consistent field (SCF) and the weakly coupled (strongly interacting) Coulomb Blockade (CB) regimes. The CB...

MCW07 Modeling Molecule-Assisted Transport in Nanotransistors
Molecular electronics faces many problems in practical device implementation, due to difficulties with fabrication and gate-ability. In these devices, molecules act as the main conducting channel. One could imagine alternate device structures where molecules act as quantum dots rather than…

MCW07 Impact of Porphyrin Functional Groups on InAs Gas Sensors
Porphyrin molecules are often used for sensor engineering to improve sensitivity and selectivity to specific analytes. It is important to understand how the porphyrin HOMO-LUMO levels deplete surface states during functionalization of solid state sensors. Additionally, the effect of...

MCW07 Simple Models for Molecular Transport Junctions
We review our recent research on role of interactions in molecular transport junctions. We consider simple models within nonequilibrium Green function approach (NEGF) in steady-state regime.

MCW07 Conductance Switching in Fluorene/TiO2 Molecular Heterojunctions
Molecular junctions consisting of a monolayer of fluorene and 10 nm of TiO2 between conducting contacts exhibit a memory effect upon positive polarization of the of the TiO2 for a few milliseconds. The junction conductance increases for a period of several minutes, but can be “erased” by a...

MCW07 Silicon Based Nanopore Sensors for Detection of DNA Molecules
Solid-state nanopores have emerged as possible candidates for next-generation DNA sequencing devices. In this talk, we will review our recent work in development of solid-state nanopore channels that are selective towards single strand DNA (ssDNA). Nanopores functionalized with a 'probe' of...

MCW07 Electronic Level Alignment at Metal-Molecule Contacts with a GW Approach
Most recent theoretical studies of electron transport in single-molecule junctions rely on a Landauer approach, simplified to treat electron-electron interactions at a mean-field level within density functional theory (DFT). While this framework has proven relatively accurate for certain systems,...

MCW07 Modeling Charging-based Switching in Molecular Transport Junctions
We will discuss several proposed explanations for the switching and negative differential resistance behavior seen in some molecular junctions. It is shown that a proposed polaron model is successful in predicting both hysteresis and NDR behavior, and the model is elaborated with image charge...
