Room-Temperature InAlAs/InGaAs Planar Tunneling-coupled Transistor
In this talk, we report the first experimental demonstration of InAlAs/InGaAs planar tunneling-coupled transistors at room temperature, in which tunneling characteristics such as negative differential resistance (NDR) and peak current are controlled with high gain [...]
Polymeric Nanowire Architectures and Nanodevices
We devised a method, named as scanned electrospinning technique, to form a variety of one-dimensional polymeric nanostructures. It is a straightforward technique that enables the rapid fabrication of oriented polymeric nanowires as well as their [...]
Nanopillar Arrays with Superior Mechanical Strength and Optimal Spacing for High Sensitivity Biosensors
Recently, many types of vertically aligned slender nanostructures, such as nanotubes and nanorods have been fabricated for use in biosensors development because of their increased surface area. Lately, evidence has emerged to reveal that these [...]

Kufazvinei C., Leahy R.W., Lipson S.M., Blau W.J., Dillon F.C., Spalding T.R., Morris M.A., Holmes J.D., Allan G., Patterson J., Trinity College Dublin, IE
The investigation aims at growing carbon nanotubes of controlled diameter from inside pores of ceramic materials. The resulting carbon nanotubes will then be used in electrons as thermally conductive substrates in die mountings.
Growth and Characterization of GaAs/AlGaAs Core-Shell Nanowires and AlGaAs Nanotubes
We report on the fabrication of GaAs/AlGaAs core-shell nanowires (NWs) and AlGaAs nanotubes by SA-MOVPE and their photoluminescence characterization. The fabrication started from a preparation of patterned GaAs (111) B substrates partially covered with SiO2 [...]
Implementation of Separable Scattering Mechanisms in Three-Dimensional Quantum Mechanical Simulations of a Silicon Quantum Wire
In order to understand the operation of any type of semiconductor device, one must consider the effects of scattering. For many years, Monte Carlo has been the workhorse that has yielded great insight into the [...]
Single-Crystal Nanowire Transistor for Logic and Memory Applications
In this paper we report chemical synthesis, device fabrication, and device physics investigation of 1-D single-crystalline nanowire field-effect transistor (SNW-FET) for logic and memory applications. Wafer-scale transistor arrays were fabricated with semiconducting nanowires serve as [...]
Electronic Transport Through Carbon Nanotubes – Effect of Contacts, Topological Defects, Dopants and Chemisorbed Impurities
Maiti A., Hoekstra J., Andzelm J., Govind N., Ricca A., Svizhenko A., Mehrez H., Anantram M.P., Accelrys Inc., US
Electronics based on carbon nanotubes (CNT) has received a lot of attention recently because of its tremendous application potential, such as active components and interconnects in nanochips, nanoelectromechanical systems (NEMS), display devices, and chemical and [...]
Spin Density Functional Theory Simulations of Quantum Point Contacts: An Investigation of Spin Filtering Effects
We present simulations of quantum wires and quantum point contacts (QPCs) formed in semiconductor heterostructures. Conductance measurements for such structures is quantized with plateaus at integer multiples of G_0= (2e^2/h) as function of gate voltage, [...]
The Design of a Silicon Wire DRAM Cell for Very Dense DRAM Architectures
In this study, we propose a new DRAM cell that uses a silicon-wire pass transistor stacked on top of a high-dielectric capacitor rated of holding industry-standard 32 fCoulomb charge. We show that the performance of [...]
Nanowire Sensors and Arrays for Chemical/Biomolecule Detection
Yun M., Lee C., Vasquez R.P., Ramanathan K., Bangar M.A., Chen W., Mulchandan A., Myung N.V., Jet Propulsion Laboratory, US
We report electrochemical growth of nanowire sensors using e-beam patterned electrolyte channels, potentially enabling the controlled fabrication of individually addressable arrays. The electrodeposition technique results in nanowires with controlled dimensions, positions, alignments, and chemical compositions. [...]
