Tunable strain and bandgap in subcritical-sized MoS2 nanobubbles

Abstract Nanobubbles naturally formed at the interface between 2D materials and their substrate are known to act as exciton recombination centers because of the reduced bandgap due to local strain, which in turn scales with the aspect ratio of the bubbles. The common understanding suggests that the...
