Realistic Modeling of Complex Surface Processes

Rohl A.L., Wright K., Gale J.D., Curtin University, AU

Computer simulation is an essential tool in nanoscale science as it yields atomic models that allow interpretation of experiment data, while also having a predictive capability. Crucially, computer simulations must be able to describe all [...]

Atomic-control Placement of Individual P atoms in Si for the Fabrication of a Quantum Computer Qubit Array

Schofield S.R., Curson N.J., Simmons M.Y., Hallam T., Ruess F.J., Oberbeck L., Clark R.G., University of New South Wales, AU

The ability to control the location of individual dopant atoms within a semiconductor has enormous potential for the creation of atomic-scale electronic devices. One of the most ambitious proposals for such a device is the [...]

On the Best Performance of Interacting Agents

Korotkich V., Central Queensland University, AU

Nanotechnology is dependent on harnessing effects of emergent systems, as it relies on the process of taking collections of molecules or individual atoms as building blocks and forming them into useful objects. Emergence can often [...]

Electronic Structure of Quantum Dots

Hines C., McCarthy S.A., Wang J.B., Abbott P.C., The University of Western Australia, AU

This paper presents a detailed calculation of the electronic structure of quantum dots with various geometries. In particular, non-circular quantum dots are examined and their characteristic properties analysed. In addition, the importance of electron-electron spin [...]

Two-Dimensional MOSFET Dopant Profile by Inverse Modeling via Source/Drain-to-Substrate Capacitance Measurement

Chiang C.Y.T., Yeow Y.T., Ghodsi R., University of Queensland, AU

This paper proposes and demonstrates a new approach to 2-dimensional dopant profile extraction for MOSFET's by treating the source/drain-to-substrate junction as a gated diode. The small-signal capacitance of the diode measured as a function of [...]

Modeling the Microstructure and Elastic Properties of Complex Materials

Roberts A.P., Garboczi E.J., University of Queensland, AU

The finite element method is used to study the influence of porosity and pore shape on the elastic properties of model porous media. The Young's modulus of each model was found to be practically independent [...]
