In this study, the nMOSFETs with contact-etch-stop-layer (CESL) stressor and SiGe channel have been fabricated with a modified 90-nm technology. The performance of nMOSFETs and stress distribution in the channel region have been investigated. The hot carrier reliability of the SiGe-channeled nMOSFETs with various CESL nitride layers has also been extensively studied. In addition, the impact of stress...
The feasibility of designing and modeling a multistage depressed collector (MDC) using 3D conformal finite-difference time-domain (CFDTD) particle-in-cell (PIC) simulations as implemented in VORPAL has been studied. A simple circuit model employing feedback mechanisms has been implemented to provide stable time-dependent voltages for each stage of the depressed collector and an arbitrary space-time...
In this work, we have derived the exact formulas for the relativistic Child-Langmuir law to describe a space charge-limited flow in a planar diode under arbitrary applied voltages. Two hypergeometric functions are obtained to relate the classic Child-Langmuir law and the ultra-relativistic formula to exact relativistic Child-Langmuir law. Both nonrelativistic-to-relativistic hypergeometric function...
Influence of ion effects on a space charge limited field emission flow has been studied systematically, by employing both analytical and numerical approaches. The analytic calculations are carried out self-consistently to yield the steady states of the bipolar flow. It is found that the field emission currents in the presence of saturated ion currents can be enhanced to be nearly 1.8, 1.5, and 1.4...

Because running all previous tests for the regression testing of a system is time-consuming, the size of a test suite of the system must be reduced intelligently with adequate test coverage and without compromising its fault detection capability. Five algorithms were designed for reducing the size of test suites where two metrics, test's function reach ability and function's test intensity, were defined...
Facility locations can appear to be a challenge for both novice and experienced analysts. But, it is far more efficient if its decision making follows a logical, systematic procedure. Such an approach markedly increases the chances of finding a location and improves the firm's objectives. This paper aims to provide Fuzzy Probability Distribution Functions (FPDF) so that the decision making can be...
A quasi-experiment was conducted in this research to investigate the feasibility of using Alice in teaching high school students programming concepts. The subjects were 166 10th-grade students from four intact classes. Alice was taught to two randomly selected classes, and the other two classes were taught C++, both for 8 weeks. The programming constructs students learned included variables, arithmetic...
