DOI: 10.1103/physrevb.103.014309
Abstract: The optical and optoelectronic properties of two-dimensional (2D) semiconductors are dominated by excitons, which usually appear as well-defined peaks in the spectral domain. Thus, detailed behaviors of excitons can be understood by tracking transient changes… read more here.

DOI: 10.1103/physrevb.99.085412
Abstract: Monolayer transition metal dichalcogenides (TMDS) are highly luminescent materials despite being sub-nanometer thick. This is due to the ultrashort ( cQ) as the generalized lower bound for allowed radiative recombination. A self-consistent methodology, which becomes… read more here.

DOI: 10.1109/jqe.2019.2936592
Abstract: The capability of nanolasers to generate coherent light in small volume resonators has made them attractive to be implemented in future ultra-compact photonic integrated circuits. However, compared to conventional lasers, nanolasers are also known for… read more here.
