Final report: A participatory method for need based capacity development projects and programmes
The three-year research project funded by MSB applies design science, in combination with traditional scientific investigation, to develop a method to guide the planning phase of capacity development projects for disaster risk reduction and climate change adaptation. The method facilitates local participation and ownership as it builds on the strengths of the Logical Framework Approach (LFA), while contextualising it to suit capacity development for disaster risk management and climate change adaptation
Semi-Empirical Model for Nano-Scale Device Simulations
We present a new semi-empirical model for calculating electron transport in
atomic-scale devices. The model is an extension of the Extended H\"uckel method
with a self-consistent Hartree potential. This potential models the effect of
an external bias and corresponding charge re-arrangements in the device. It is
also possible to include the effect of external gate potentials and continuum
dielectric regions in the device. The model is used to study the electron
transport through an organic molecule between gold surfaces, and it is
demonstrated that the results are in closer agreement with experiments than ab
initio approaches provide. In another example, we study the transition from
tunneling to thermionic emission in a transistor structure based on graphene
nanoribbons.Comment: 8 pages, 8 figures. Submitted to PR
