2006 PhD Physics from Brown
Guohua graduated with a PhD in physics in 2006, completing the work on inhomogeneous strain and resulting lateral quantum confinement in Si/SiGe nanostructures.
His PhD thesis was entitled The Physics of Strain-Induced Quantum Confinements in Si/SiGe Vertical Quantum Dots., including elliptically shaped nanostructures.
After Brown he returned to China to work in the semiconductor industry.
