In this paper, a semi-analytical model for the dispersion relation of nanowire lasers is presented. The approach which is based on the multi-conductor transmission line modeling, makes use of the Fourier expansion technique. The cross-section of the nanowire is assumed to be hexagonally-shaped. To determine the accuracy, the model results are compared to the numerical results obtained from FDTD...

Using a conductive atomic force microscope (c-AFM) redox-writing technique, it is shown that it is possible to locally, and reversibly, pattern conducting, and nonconducting features on the surface of a low molecular weight aniline-based organic (semi)-conductor thin film using a commercial c-AFM. It is shown that application of a voltage between the tip and sample causes localized redox reacti...

The compound CeCuAs2 is found to exhibit negative temperature (T) coefficient of electrical resistivity (ρ) under ambient pressure conditions in the entire T-range of investigation (45 mK to 300 K), even in the presence of high magnetic fields. Preliminary tunneling spectroscopic measurements indicate the existence of a psuedo-gap at least at low temperatures, thereby implying that this compoun...

Motivated by the yield optimization problem in semi-conductor manufacturing, we model the wafer to wafer integration problem as a multi-dimensional assignment problem and study it from an approximation point of view. We give approximation algorithms achieving an approximation factor of 3 2 and 4 3 for WWI-3. We show that a special case of yield optimization problem can be solved in polynomial t...

Discussed in this paper is the appl icat ion of “Moving-Bel t P lasma-Fac ing Components” for steady-state impurity g e t t e r i n g , heat removal and tritium recovery in f u s i o n reactors. To minimize MHD effects as well a s induced radioactivity, semi-metallic or s e m i conductor materials such as C-C composite o r SiC-SiC composite fabrics are proposed as t h e belt materials.
