Optical modulators are central to a large number of applications in photonics particularly in the area of communication as they provide the function of writing electrical data onto an optical carrier. Silicon photonics provides a route to the realisation of low cost photonic integrated circuits through fabrication which is synonymous with CMOS electronic fabrication, i.e., high volume and high yield...
Hydrogen is an element of significant interest for semiconductor process; however it cannot be detected by many available elemental analysis techniques. Secondary ion mass spectrometry (SIMS) is one of the few techniques for the measurement of hydrogen amount and depth distribution. Among all kinds of SIMS tools, magnetic sector, quadrupole and time-of-flight, quadrupole SIMS instrument usually has...
MnGa compounds possess several fascinating and useful properties, such as a large magnetocrys-talline anisotropy Ku, a high spin polarization P, a high Curie temperature TC and a flexible magnetization M. These results suggest that MnGa compounds are of potential candidates for spin-transfer-torque and rare-earth-free permanent magnet applications [1-2]. There are two most interesting tetragonal phases,...
This paper discusses the effect of pulse repetition rates on silicon wafer modification by four-beam laser interference. In the work, four-beam laser interference was used to pattern single crystal silicon wafers for the fabrication of dots, and different laser pulse repetition rates were applied to the process in the air. The results were obtained from 10 laser exposure pulses with the single laser...
A self--scheduling model of cascaded hydropower stations in day-ahead energy market is established in the paper. The objective of the model is to maximize generation profit. The multi stage model is nonlinear and contains complex constraints. To solve such a model is a challenging task. In this paper, Nonlinear Complementarity Method is proposed to solve the model The Karush-Kuhn-Tucker condition...
Screen printable etch paste was developed for low cost patterning of dielectric films. This technique offers a simple print and bake approach to pattern without the need for a rinse step. Residue analysis of the etched area showed no sign of any organic residue left behind by the etch process. High carrier lifetime indicates no significant contamination or silicon surface damage. The etched via diameter...
This article presents an edge detection method using fast Bidimensional EMD and mathematical morphological methods. It is shown that the detection results are better than other comparable algorithms. The optimization of the presented algorithm extracts sufficient features for intended applications.
The theory of Variable Structure Systems (VSS) is extended to three-segment VSS. This is an effective means to insensitize a system to parameter variations and disturbances. The sliding mode region is extended and the response can start and stay on the sliding mode from the initial to final running time. Example are given to illustrate the effectiveness of the proposed method. Analysis shows the superiority,...
