Bakgrunn og aktiviteter
A Ph.D Candidate at the Department of Materials Science and Engineering.
My education consists of a B.Sc and M.Sc in the study programme Materials science and Nanotechnology from the University of Oslo. The topic of the M.Sc thesis was lattice thermal conductivity in (Ti, Zr, Hf)NiSn half-Heusler alloys based on first principles calculation and the Boltzmann transport equations for heat transport.
I am currently studying multricrystalline silicon (mc-Si) for solar cell applications. The production of mc-Si results in unwanted defects, such as dislocations. The goal of the poject is to acquire a fundamental understanding through atomistic and mesoscale modelling of the initiation and evolution of dislocations during growth or cooling of mc-Si. Various simulation techniques will be assesed, such as, Density Functional Theory, Molecular Dynamics and Kinetic Monte Carlo.
