Observation of coupling between zero- and two-dimensional semiconductor systems based on anomalous diamagnetic effects
Shuo Cao, Jing Tang, Yue Sun +13
We report the direct observation of coupling between a single self-assembled InAs quantum dot and a wetting layer, based on strong diamagnetic shifts of many-body exciton states us…
Longitudinal wave function control in single quantum dots with an applied magnetic field
Shuo Cao, Jing Tang, Yunan Gao +10
Controlling single-particle wave functions in single semiconductor quantum dots is in demand to implement solid-state quantum information processing and spintronics. Normally, part…
Substrate effects on quasiparticles and excitons in graphene nanoflakes
W. Sheng, M. Sun, A. Zhou +1
The effects of substrate on electronic and optical properties of triangular and hexagonal graphene nanoflakes with armchair edges are investigated by using a configuration interact…
Tuning the exciton g-factor in single InAs/InP quantum dots
D. Kim, W. Sheng, P. J. Poole +6
Photoluminescence data from single, self-assembled InAs/InP quantum dots in magnetic fields up to 7 T are presented. Exciton g-factors are obtained for dots of varying height, corr…
Atomistic theory of electronic and optical properties of InAs/InP self-assembled quantum dots on patterned substrates
Weidong Sheng, Pawel Hawrylak
We report on a atomistic theory of electronic structure and optical properties of a single InAs quantum dot grown on InP patterned substrate. The spatial positioning of individual…
Multiband theory of multi-exciton complexes in self-assembled quantum dots
Weidong Sheng, Shun-Jen Cheng, Pawel Hawrylak
We report on a multiband microscopic theory of many-exciton complexes in self-assembled quantum dots. The single particle states are obtained by three methods: single-band effectiv…
