Nanoscale Activated Field on Cermic Electret In Pseudobiological Environment
A pseudo-biological environment using simulated body fluid (SBF) has been widely accepted as an osteobonding estimation of biomaterial surfaces. In the present study, the interactions at the interface of the polarized HA surface and the [...]
High Resolution Compton Imaging of Nanostructures
We describe a novel and unique imaging technique based on Compton scattering, a fundamentally different physical process than those based on photo-absorption techniques (such as XPS and its variants UPS/SRPS). This is unique since it [...]
Growth of InAs Quantum Dots Using the Strained Superlattices and Their Optical Properties
Leem J-Y, Choi H-K, Jeon M.H., Lee J.W., Leem J-Y, Cho G.S., Choi H-K, Department of Optical Engineering, KR
we have studied the growth of self-assembled quantum dots (QDs) using Stranski-Krastanow growth mode and strain-reducing layers for long-wavelength applications with narrow linewidth in photoluminescence (PL) emission. InAs QDs were grown on the strained superlattices, [...]

Magnetic Antidot Arrays with a Storage Density of 10 Gbits/cm2
Xiao Z.L., Han C.Y., Welp U., Wang H.H., Willing G.A., Vlasko-Vlasov V.K., Kwok W.K., Miller D.J., Hiller J.M., Cook R.E., Crabtree G.W., Argonne National Laboratory, US
Large area nickel antidot arrays with density up to 10^10 /cm^2 have been fabricated by depositing nickel onto anodic aluminum oxide (AAO) membranes that contain lattices of nanopores. Electron microscopy images show a high degree [...]
Low Temperature Electronic Properties of Electrospun PAN-Derived Carbon Nanofiber
The possible sensor application of carbon nanofibers relies on the nanofibers electronic transport. This paper fabricated carbon nanofibers using electrostatic deposition and vacuum pyrolysis techniques. Scanning electron microscope (SEM) and scanning probe microscopes (SPM) images [...]
Mechanical and Semiconductor Properties of Nanophase Amorphic Diamond Coatings for High Power Electronics
The mechanical and semiconductor properties of amorphic diamond can be employed to improve the high power photoconductive semiconductor switch longevity by coating the switch cathode or anode areas or both. In this work issues concerning [...]
Electron Sources for Massively Parallel Electron Beam Lithography System using Single Vertically Aligned Carbon Nanofiber Cathodes
Guillorn M.A., Whealton J.H., Baylor L.R., Melechko A.V, Merkulov V.I., Hensley D.K., Hale M.D., Kasica R.J., Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US
Electron beam lithography using a single beam cannot achieve acceptable throughput levels to become a viable manufacturing technology. The digital electrostatic e-beam array lithography (DEAL) concept under development at the Oak Ridge National Laboratory proposes [...]
Nanoelectronic Devices Constructed Using Individual Vertically Aligned Carbon Nanofibers
