Multiscale computational simulations are performed to investigate how electronic structure and optical absorption characteristics of recently reported nanostructured III-nitride core-shell multiple quantum well (MQW) solar cells are governed by an intricate coupling of size-quantization, atomicity, and built-in structural and polarization fields. The core computational framework is divided into four...
This work describes our on-going efforts to develop a multiscale Quantum Atomistic Device Simulator (QuADS 3-D) where: a) material parameters are obtained atomistically using first-principles, b) structural relaxation and phonon dispersions are studied via molecular mechanics/dynamics, c) a variety of tight-binding models (s, sp3s*, sp3d5s*) are used for the calculation of electronic bandstructure...
The ionospheric delay in the propagation of Global Positioning System (GPS) signal is one of the main sources of error in GPS precise positioning. Therefore, it is important to have a precise estimation of the ionospheric delays. A new approach in the determination of the differential (between spaced receivers) ionospheric error to sub-centimetre accuracy is described in this paper utilising a developed...
