Abstract: In problem-based learning students are presented with a problem as the motivation for group research. The presentation of the problem attempts to address the issue of ownership of content by both providing a context for knowledge acquisition and requiring a transformation of material to address the problem. The transformational aspect in principle provides the opportunity for creativity. We present two case studies, with different outcomes, and the results of a workshop, in which visual imagery was used as the hook for a PBL problem with a view to encouraging creativity in the responses.2016-05-12T11:14:04ZSaturn's Seasonal Atmosphere: Temperatures, Clouds and CompositionFletcher, Leigh NicholasGreathouse, T.

Abstract: An efficient method for calculation of self-assembled dot states within the effective mass approximation is described and its application to the calculation of Auger relaxation rates is detailed. The method is based on expansion of the dot states in a harmonic oscillator basis whose parameters are optimised to improve the convergence rate. This results in at least an order of magnitude reduction in the number of basis states required to represent electron states accurately compared to the conventional plane wave approach. Auger relaxation rates are calculated for harmonic oscillator model states and exact states for various pyramidal models. The dipole approximation, previously used to calculate Auger rates, is found to be inaccurate by a factor of around 2–3. The harmonic oscillator states do not reproduce the rates for the more realistic pyramidal models very well and even within the set of pyramidal models variations in the dot shape and size can change the rates by up to an order of magnitude. Typical Auger relaxation rates are on a picosecond timescale but the actual value is strongly dependent on the density of electrons outside the dot.
