Paper Abstract

We demonstrate the rolling process of strained III-V compound semiconductor films upon epitaxial liftoff from the substrate. The formed tubular structures with diameters in the micron range, embedded with quantum confined GaAs light emitters in the ultra-thin tube walls (< 100 nm) show dramatic enhancement in intensity and reduction of bandgap as a function of tube curvature. Emission characteristics and implications are analyzed.
