Introduction to Organic Thin Film Transistors and Design of n-Channel Organic Semiconductors
The development of new organic semiconductors with improved performance in organic thin film transistors (OTFTs) is a major challenge for materials chemists. There is a particular need to developExpand
Transition from direct tunneling to field emission in metal-molecule-metal junctions.
Current-voltage measurements of metal-molecule-metal junctions formed from pi-conjugated thiols exhibit an inflection point on a plot of ln(I/V(2)) vs 1/V, consistent with a change in transportExpand
Comparison of Electronic Transport Measurements on Organic Molecules
We compile, compare, and discuss experimental results on low bias, room-temperature currents through orgnaic molecules obtained in different electrode-molecule-electrode test-beds. Currents areExpand
Printable ion-gel gate dielectrics for low-voltage polymer thin-film transistors on plastic.
It is demonstrated that an emerging class of polymer electrolytes known as ion gels can serve as printable, high-capacitance gate insulators in organic thin-film transistors, enabling transistor operation at low voltages with kilohertz switching frequencies. Expand
Chemical Force Microscopy: Exploiting Chemically-Modified Tips To Quantify Adhesion, Friction, and Functional Group Distributions in Molecular Assemblies
Chemical force microscopy (CFM) has been used to measure adhesion and friction forces between probe tips and substrates covalently modified with self-assembled monolayers (SAMs) that terminate inExpand
Electrolyte-gated transistors for organic and printed electronics.
Recent progress in the development of electrolyte-gated transistors (EGTs) for organic and printed electronics is summarized and key developments in electrolyte materials for use in printed electronics are reviewed. Expand
Length-dependent transport in molecular junctions based on SAMs of alkanethiols and alkanedithiols: effect of metal work function and applied bias on tunneling efficiency and contact resistance.
Nanoscopic tunnel junctions were formed by contacting Au-, Pt-, or Ag-coated atomic force microscopy (AFM) tips to self-assembled monolayers of alkanethiol or alkanedithiol molecules on polycrystalline Au, Pt, or Ag substrates to study length-dependent decay parameter and contact resistance. Expand
Size- and temperature-dependent charge transport in PbSe nanocrystal thin films.
The size- and temperature-dependence of electron transport in thin films of PbSe nanocrystals is reported and the activation energy from the NNH regime was size-dependent, which is attributed both to size- dependent Coulomb effects and the size-distribution of nanocrystal. Expand
Functional Group Imaging by Chemical Force Microscopy
By monitoring the friction between a specifically functionalized tip and sample, one can produce friction images that display predictable contrast and correspond to the spatial distribution of functional groups on the sample surface. Expand

Metal-molecule-metal junctions fabricated by contacting Au-supported alkyl or benzyl thiol self-assembled monolayers with an Au-coated atomic force microscope (AFM) tip show that conducting probe-AFM is a reliable method for fundamental studies of electron transfer through small numbers of molecules.
