Abstract: Ultrathin mechanical structures are ideal building platforms to purse the ultimate limit of nanomechanical resonators for applications in sensing, signal processing and quantum physics. Unfortunately, as the thickness of the vibrating structures is reduced, the… read more here.

Abstract: We investigate the optical properties of strain-free mesoscopic GaAs/Al(x)Ga(1-x)As structures (MGS) coupled to thin GaAs/A(x)Ga(1-x)As quantum wells (QWs) with varying Al content (x). We demonstrate that quenching the QW emission by controlling the band crossover… read more here.
