N2 - In this study, we investigate the effects of stress/strain on the band structures of self-rolled GaAs/Al0.26 Ga 0.74As quantum wells (QWs). The results show that the two QWs are in different stress/strain statuses and the boundary line locates between the two QWs. Based on spectral characterizations under different bias voltages, we disclose that interface polarization exists in self-rolled nanomembrane. In addition, we find that the responsivity of the QW in tensile strain is higher than that in compressive strain, and therefore we fabricated a self-rolled-down tubular structure with both two QWs in tensile strain to increase the responsivity by ∼52%.
