Machine-learning-enabled methodology for the ab-initio simulations of sub-m-wide nanoribbons
Guan-Hao Peng, Chin-Jui Huang, Wen-Teng Yang +1
Simulation of mesoscopic nanostructures is a central challenge in condensed matter physics and device applications. First-principles methods provide accurate electronic structures…
Enhanced photo-excitation and angular-momentum imprint of gray excitons in WSe monolayers by spin-orbit-coupled vector vortex beams
Oscar Javier Gomez Sanchez, Guan-Hao Peng, Wei-Hua Li +3
A light beam can be spatially structured in the complex amplitude to possess orbital angular momentum (OAM), which introduces a new degree of freedom alongside the intrinsic spin a…
The key role of non-local screening in the environment-insensitive exciton fine structures of transition-metal dichalcogenide monolayers
Wei-Hua Li, Jhen-Dong Lin, Ping-Yuan Lo +4
In this work, we present a comprehensive theoretical and computational investigation of exciton fine structures of WSe-monolayers, one of the best known two-dimensional (2D) tr…
Twisted-light-induced exciton wave packets in transition-metal dichalcogenide monolayers
Guan-Hao Peng, Oscar Javier Gomez Sanchez, Wei-Hua Li +2
We present a comprehensive theoretical investigation of the photo-generated excitons in transition-metal dichalcogenide monolayers (TMD-ML's) by Laguerre-Gaussian beams, a celebrat…
Wavelength extension beyond 1.5 micrometer in symmetric InAs quantum dots on InP(111)A using droplet epitaxy
N. Ha, T. Mano, Y. -N. Wu +5
By using a C3v symmetric (111) surface as a growth substrate, we are able to achieve high structural symmetry in self-assembled quantum dots, which are suitable for use as quantum-…
Size dependent line broadening in the emission spectra of single GaAs quantum dots: Impact of surface charges on spectral diffusion
N. Ha, T. Mano, Y. L. Chou +8
Making use of droplet epitaxy, we systematically controlled the height of self-assembled GaAs quantum dots by more than one order of magnitude. The photoluminescence spectra of sin…
