Resonant Raman Scattering from Quasi-2D Van Hove Excitons in Strain-Engineered Germanium Microstructures

Abstract We present a sub-μm spatial resolution Raman mapping study of strain-engineered germanium (Ge) micro-bridge structures, fabricated on a 220 nm silicon-on-insulator (Ge-SOI). Revision of the analytical geometric-strain model for such structures, to account for partial und...
