Simulation based electrostatic study of different multigate quantumwell field effect transistors by changing the gate oxide thickness and metal work function
(BRAC University, 2016)
This paper analyses the C-V characteristics by altering the gate oxide thickness and metal workfunction used in the gate of non-planer, multi-gate InGaAs channel Quantum Well Field-Effect Transistor (QWFET). In this paper, ...
Wimax security analysis
(Department of Electrical and Electronic Engineering, 2011-04-28)
Worldwide Interoperability for Microwave Access (WiMAX) is a wireless metropolitan area network (WMAN) communications technology using the IEEE 802.16 standard. The original purpose of IEEE 802.16 technologies was to provide ...
A comparative study of DC/AC pure sine wave inverters
(BRAC University, 2013-12)
A power inverter or inverter is an electrical power converter that changes direct current (DC) to alternating current (AC). The converted AC can be at any required voltage and frequency with appropriate transformer, switching ...
Optimisation of photonic crystal weveguide based optical filter
(BRAC University, 2013-04)
Photonic integrated circuits (PIC) based on Photonic Crystals are becoming increasingly favoured in emerging signal processing and optical communication technologies. Photonic crystals (PhCs) are periodic dielectric ...
People mover project (control system part)
(BRAC University, 2011-12-07)
People-Mover is an electrical self-motivated medium. The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks, but is sometimes applied to ...
Performance analysis of dye sensitized solar cell based on ZnO compact layer and TiO2 photoanode
(BRAC University, 2018-08)
Harnessing solar energy as an alternative solution to power production. Power can
