Abstract
We fabricated quantum well (QW) microtubes by rolling up thin films containing QWs and measured their photoluminescence (PL) properties. Before fabricating microtubes, no PL signal is observed in the QW at all, because their band configuration is indirect, i.e., type-II. However, PL signal is detected in the QW microtubes. This result clearly indicates that the transition from type-II to type-I band configuration of QW microtubes is induced by uniaxial-strain effect.
