Research Projects


I am currently studying nitridosilicates, which are a class of materials that have a number of interesting physical properties, including good thermal conductivity and high strength and hardness. They are also of interest in lighting applications owing to their high efficiency in phosphor-conversion based LEDs. The goal is to characterize the electronic structure of these materials so that we may develop materials with tunable band gaps. Since the physical properties of a material are determined by the electronic structure, its characterization can lead to predictions about the properties of similar materials, such as their hardness, which has been correlated with the band gap.
