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…

Inherently high valley polarizations of momentum-forbidden dark excitons in transition-metal dichalcogenide monolayers

Ping-Yuan Lo, Guan-Hao Peng, Wei-Hua Li +2

High degree of valley polarization of optically active excitons in transition-metal dichalcogenide monolayers (TMD-MLs) is vital in valley-based photonic applications but known to…

Symmetry governed valley-pseudospin textures of the full-zone excitonic bands of transition-metal dichalcogenide monolayers

Ping-Yuan Lo, Guan-Hao Peng, Wei-Hua Li +2

Preserving a high degree of valley polarization of excitons in photo-excited transition-metal dichalcogenide monolayers (TMD-MLs) is desirable for the valley-based photonic applica…

Twisted-light-revealed Lightlike Exciton Dispersion in Monolayer MoS2

Kristan Bryan Simbulan, Teng-De Huang, Guan-Hao Peng +7

Twisted light carries a well-defined orbital angular momentum (OAM) per photon. The quantum number l of its OAM can be arbitrarily set, making it an excellent light source to reali…

Distinctive signatures of the spin- and momentum-forbidden dark exciton states in the photo-luminescences of strained WSe monolayers under thermalization

Guan-Hao Peng, Ping-Yuan Lo, Wei-Hua Li +5

With the both spin and valley degrees of freedom, the low-lying excitonic spectra of photo-excited transition-metal dichalcogenide monolayers (TMDC-MLs) are featured by rich fine s…

Optimal electro-mechanical control of the excitonic fine structures of droplet epitaxial quantum dots

Shun-Jen Cheng, Yi Yang, Yu-Nien Wu +2

The intrinsic fine structure splittings (FSSs) of the exciton states of semiconductor quantum dots (QDs) are known to be the major obstacle for realizing the QD-based entangled pho…
