ABOUT THE RESEARCH GROUP
The nano engineering group uses numerical methods to turn nano-science into nanotechnology. One example is our current focus on numerical optimisation of up-converting media for use in solar cells. The materials are nano structured with particles which focus the incoming light. Up-converting rare-earth atoms or nano particles are placed in the focused light and will convert it from long wavelength to short wavelength. The short wavelength light can then be absorbed in a solar cell, thereby boosting its efficiency. We apply parameter and topological optimisation to find the optimal nano-structures.
Another example is our focus on atomistic simulations of of nano-structures, for example to understand the processes in the fabrication of nano particles by vapor deposition methods, or to understand the elastic properties of nano wires.
