We have measured the low-temperature conductance of a one-dimensional island embedded in a single mode quantum wire. The quantum wire is fabricated using the cleaved edge overgrowth technique and the tunneling is through a single state of the island. Our results show that while the resonance line shape fits the derivative of the Fermi function the intrinsic linewidth decreases in a power law fa...

Our work supplements [3] very closely, even down to the level of notation. The setting is three-dimensional xyz-space. 0.1. Six Edges of a Cube. Consider a polygonal wire loop with six line segments: (0, 0, 0)→ (1, 0, 0)→ (1, 0, 1)→ (1, 1, 1)→ (0, 1, 1)→ (0, 1, 0)→ (0, 0, 0). What is the minimal area for any surface spanning this fixed boundary? Equivalently, what is the outcome of dipping the ...

This work provides a comprehensive analytical analysis of one‐selector‐one‐resistor (1S1R) crossbar array (CBA) device for hardware neural network (HNN) applications. Simplified models are prepared from particular 1S1R to validate the analysis. The read margin (RM) results show that V /3 voltage scheme and reduced selector leakage necessary maximize RM maximum operable size N CBA, where indicat...

A low voltage electropolishing of metal wires is attractive for nanotechnology because it provides centimeter long and micrometer thick probes with the tip radius of tens of nanometers. Using X-ray nanotomography we studied morphological transformations of the surface of tungsten wires in a specially designed electrochemical cell where the wire is vertically submersed into the KOH electrolyte. ...

Supervisory Committee Dr. Thomas Edward Darcie, (Department of Electrical and Computer Engineering) Supervisor Dr. Jens Bornemann, (Department of Electrical and Computer Engineering) Departmental Member Dr. Colin Bradley, (Department of Mechanical engineering) Outside Member In this thesis, novel broadband waveguides capable of operating at terahertz (THz) frequencies are introduced. We explore...

Graphic processing unit (GPU), which contains hundreds of processing cores, is becoming a popular device for high performance computation in multi-core era. With strictly computation regularity characteristic, specific algorithms are key challenges for performance speed-up. In this paper, we propose a parallel CUDA-Mikami routing algorithm on NVIDIA’s GPU. A 32-bit routing grid encoding is prop...

We have calculated the optical absorption spectra of magnetoexcitons in T-wire semiconductor. It is calculated using the semiconductor Bloch equations in time and real-space domains. The peak and the linewitdth of the fundamental exciton transition are investigated as a function of the applied magnetic and static electric field. The latter is applied along the wire axis and induces a broadening...

Here we proposed lithography based layer decomposition for reduced wire length three-layer routing solution using Double Patterning Technology (DPT). First we proposed a routing algorithm of three-layer (HVH) restricted dogleg routing solution to minimize the wire length of the chip to be designed. Next we designed a layer decomposition algorithm of the obtained routing solution using DPT to in...

With two sets of photo couplers, scientists already have applied pulsed-wire method (PWM) to measure the magnetic field along two mutually perpendicular directions. The authors believe that two-dimensional pulsed-wire method is useful for the test of elliptically polarizing undulator (EPU). We tried to use this method to observe the first integral and second integral fields of a short EPU in re...

During the reconstruction of the ISOLDE on-line mass separator facility at CERN one of the goals was the development and implementation of an efficient and user friendly beam observation system. The pick-up devices used on the two mass separators and the beam lines are mainly Faraday cups, wire scanners and wire grids. Most of these items were specifically designed at ISOLDE, in particular, a l...
