I'm a first year graduate student in the Electrical Engineering department at UC Berkeley working with the Yablonovitch group. Previously, I was an undergrad at MIT, where I researched with the Buonassisi group. My current research focuses on improving solar cell efficiency with metal optics.
Infrared Birefringence Imaging: Upon applying stress, photoelastic materials (such as silicon), become birefringent. We used infrared birefringence imaging to evaluate the mechanical strength of multicrystalline silicon wafers. This work was done in collaboration with the Fraunhofer Institute for Mechanics of Materials in Halle, Germany, where I spent a summer through the support of MISTI-Germany.
Paper: Infrared birefringence imaging of residual stress and bulk defects in multicrystalline silicon.
