High-resolution spectroscopy of a quantum dot driven bichromatically by two strong coherent fields
Physical Review Research, 2021 We present spectroscopic experiments and theory of a quantum dot driven bichromatically by two strong coherent lasers. In particular, we explore the regime where the drive strengths are substantial enough to merit a general nonperturbative analysis ...

Sb2S3 Quantum-Dot Sensitized Solar Cells with Silicon Nanowire Photoelectrode
International Journal of Photoenergy, 2015 We propose a novel quantum-dot sensitized solar cell (QDSSC) structure that employs a quantum dot/semiconductor silicon (QD/Si) coaxial nanorod array to replace the conventional dye/TiO2/TCO photoelectrode.

Theoretical study of intraband optical transitions in conduction band of dot-in-a-well system
AIP Advances, 2014 We study numerically absorption optical spectra of n-doped InAs/In015Ga085As/GaAs quantum dot-in-a-well systems. The absorption spectra are mainly determined by the size of a quantum dot and have weak dependence on the thickness of quantum well and ...
