Bulk Heterojunction Organic-Inorganic Photovoltaic Cell Based on Doped Silicon Nanowires

Goncher G., Noice L., Solanki R., Portland State University, US

A bulk heterojunction organic-inorganic photovoltaic cell was fabricated by growing doped n-type silicon nanowires on an n+ silicon substrate. A p-type organic semiconductor (P3HT) was then coated over the nanowires. The device was completed by [...]

Electroluminescence of ZnO Nanowire/p-GaN Heterojunction Light Emitting Diodes

Wang X., Cole J.J., Jacobs H.O., University of Minnesota, US

ZnO nanowire/p-GaN heterojunction light emitting diodes (LEDs) were fabricated by growing ZnO nanowire vertical arrays in aqueous solution on Mg-doped p-GaN films. Diode-like, rectifying I-V characteristics were recorded at room temperature and a “current crowding” [...]

Growth and Engineering of High Aspect-Ratio AAO Templates Integrated on Silicon Substrates

Choi S., Daugherty M., Enable IPC Corporation, US

We have developed a CMOS-compatible process for manufacturing nanowires directly on silicon (or other) substrates. This process removes some of the steps for conventional nanowire manufacture. The result are highly-ordered, high aspect-ratio nanowires for use [...]

Manufacturable, Highly Responsive Nanowire Mercury Sensors

Keebaugh S., Nam W.J., Fonash S.J., The Pennsylvania State University, US

We have developed a manufacturable and highly responsive gold nanowire sensor capable of detecting ppb concentrations of mercury in air and water. The nanowire sensor exhibits a superior response compared to thin film sensors and [...]

Investigation of the Conductance of Silicon Nanowire Biosensors Using the 2D Drift-diffusion Model

Damodaran S., Vadivelmurugan S., Do Q.T., Heitzinger C., Liu Y., Klimeck G., Purdue University, US

DNA-FETs are DNA sensors consisting of a semiconductor transducer and a functionalized surface. Their device structure is similar to a MOSFET, but the gate has been replaced by the functionalized surface. Since DNA-FETs allow direct [...]

Mechanics of silicon nanowires: size-dependent elasticity from first principles

Rudd R.E., Lee B., Lawrence Livermore National Laboratory, US

We have conducted a detailed study of the size dependence of the mechanical properties of silicon nanowires using first principles quantum mechanical calculation together with continuum mechanics theory and atomistic simulation based on empirical potentials. [...]

Synthesis of three-dimensional Mn3O4 nanostructures

Du C.S., Yun J.D., Browning N., Pan N., University of California at Davis, US

Owing to the large specific surface area and other superior properties over their bulk counterparts arising from quantum size effect, nanoscaled and nanostructured materials have attracted considerate research interest and many novel nanoscale materials have [...]

Thickness-controlled Metal Nanoscale Etch for Proposed Metal Nanowires Fabrication

Lee B.C., Kim M.H., Shin H-J, Moon S., Korea Institute of Science and Technology, KR

In this works, we developed a novel nanoscale etch process of metallic structures, the metal peel-off method(MPOM), to realize proposed fabrication of metal nanowires. Using this method, we simply and uniformly self-controlled etching rate of [...]

Silicon Nanowire Transistors Fabricated by the Mass-Manufacturable, Self-Assembling “Grow-in-Place” Approach

Shan Y., Fonash S.J., Pennsylvania State University, US

Silicon nanowire (SiNW) transistor fabrication, until our work, has had environmental concerns and manufacturing issues arising from the use of a complex process flow involving SiNW growth and harvesting followed by nanowire positioning, aligning and [...]
