Device structures and device simulation techniques

آنالیز مقایسه ای روشهای بهبود اثرات کوچک سازی کانال در ترانزیستورهای SOI-MOSFET و ارائه یک تکنیک جدید

This paper critically examines the Short Channel Effects (SCEs) improvement techniques for improving the performance of SOI-MOSFETs.  Also for first time, a new device structure called the Shielded Channel Multiple-Gate SOI-MOSFET (SC-MG) is introduced and designed. Using two-dimensional and two-carrier device simulation, it is demonstrated that the SC-MG exhibits a significantly reduced the el...

Semi-active Control of Building Structures using Variable Stiffness Device and Fuzzy Logic

Semi-active control devices, also called “Intelligent” control devices, constitute the positive aspects of both the passive and active control devices. A semi-active control strategy is similar to the active control strategy, but this control device has been shown to be more energy-efficient than active devices. A particular type of semi-active control device, the Variable Stiffness Device (VSD...

Simulation of environmental dose distribution of nuclear gauge device MC-1DR by MCNPX code

In this study, distribution of dose rate around the nuclear gauge device MC-1DR which located in shahrekord university was simulated by MCNPX code and was compared whit the measured values. Due to the asymmetry of device and neutron and gamma source positions, the dose rates were determined at a distance of 5, 30 and 100 cm in different directions. Base on the complex geometry of the inside of ...

Review, analysis and simulation of different structures for hybrid electrical energy storages

Output power in a hybrid power system is constant while the input power with variable characteristics that is generated by different sources. Using Hybrid Electrical Energy Storage (HEES) systems, is growing rapidly since there is an obvious need for clean energy. This paper introduces different parts of a HEES system and then proposes HEES systems which employ battery, ultracapacitor and f...

Investigation and Simulation of the Effects of Dispersion and Transmittance angles on the Solar Cells Quantum Efficiency

In this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (QESC) have been simulated and investigated. Optical path technic is used for simulation. The results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the QESC. Simulation r...
