Gated Chemical Transport through Vertically Aligned Carbon Nanotube Membranes

A promising architecture for ion-channel mimetics is a composite membrane structure containing vertically aligned carbon nanotubes, with inner core diameters of 7 nm, passing across a polystyrene matrix film. Plasma oxidation during the fabrication process introduces carboxylic acid groups on the C…

Theory of Ballistic Nanotransistors

Numerical simulations are used to guide the development of a simple analytical theory for ballistic field-effect transistors. When two-dimensional electrostatic effects are small, (and when the insulator capacitance is much less than the semiconductor (quantum) capacitance), the model reduces to Nat…

Simple Theory of the Ballistic MOSFET

Silicon nanoelectronics has become silicon nanoelectronics, but we still analyze, design, and think about MOSFETs in more or less in the same way that we did 30 years ago. In this talk, I will describe a simple analysis of the ballistic MOSFET. No MOSFET is truly ballistic, but approaching this fami…

Towards a Terahertz Solid State Bloch Oscillator

The concepts of Bloch oscillation and Zener breakdown are fundamental to electron motion in periodic potentials and were described in the earliest theoretical developments of electron transport in solids. But only in the past 10 years have experiments clearly demonstrated various aspects of Bloch os…

Quantum Electromechanical Systems: Are we there yet?

Note: The video for this presentation has been lost and is no longer available.Electrons moving in a conductor can transfer momentum to the lattice via collisions with impurities and boundaries, giving rise to a fluctuating mechanical stress tensor. Driving electrons out of equilibrium by applying …

Control of Exchange Interaction in a Double Dot System

As Rolf Landauer observed in 1960, information is physical. As a consequence, the transport and processing of information must obey the laws of physics. It therefore makes sense to base the laws of information processing and computation on the laws of physics and in particular on quantum mechanics. …

Electronic Transport Through Self-Assembled Monolayers

Characterization of charge transport in molecular scale electronic devices has to date shown exquisite sensitivity to specifics of device fabrication and preparation. Thus, intrinsic molecular band structure has been problematic to extract from published results. Here we demonstrate cross-platform d…

Faster Materials versus Nanoscaled Si and SiGe: A Fork in the Roadmap?

Strained Si and SiGe MOSFET technologies face fundamental limits towards the end of this decade when the technology roadmap calls for gate dimensions of 45 nm headed for 22 nm. This fact, and difficulties in developing a suitable high-K dielectric, have stimulated the search for alternatives to brut…

Nanoelectronics and the Future of Microelectronics

Progress in silicon technology continues to outpace the historic pace of Moore's Law, but the end of device scaling now seems to be only 10-15 years away. As a result, there is intense interest in new, molecular-scale devices that might complement a basic silicon platform by providing it with ne…
