Layer-controlled band gap and anisotropic excitons in few-layer black phosphorus
The authors report that the band structure of few-layer black phosphorous is anisotropic and the band gap increases with the decrease in number of staking layers. The optical absorption and excitonicExpand

Carrier plasmon induced nonlinear band gap renormalization in two-dimensional semiconductors.
In reduced-dimensional semiconductors, doping-induced carrier plasmons can strongly couple with quasiparticle excitations, leading to a significant band gap renormalization. However, the physicalExpand

Van Hove singularities and excitonic effects in the optical conductivity of twisted bilayer graphene.
We report a systematic study of the optical conductivity of twisted bilayer graphene (tBLG) across a large energy range (1.2-5.6 eV) for various twist angles, combined with first-principlesExpand

Optically Discriminating Carrier-Induced Quasiparticle Band Gap and Exciton Energy Renormalization in Monolayer MoS_{2}.
Optoelectronic excitations in monolayer MoS_{2} manifest from a hierarchy of electrically tunable, Coulombic free-carrier and excitonic many-body phenomena. Investigating the fundamental interactionsExpand

Preparation and characterization of folate-poly(ethylene glycol)-grafted-trimethylchitosan for intracellular transport of protein through folate receptor-mediated endocytosis.
To develop a receptor-mediated intracellular delivery system that can transport therapeutic proteins to specific tumor cells, folate-poly(ethylene glycol)-grafted-trimethylchitosan (folate-PEG-g-TMC)Expand

Dynamical Excitonic Effects in Doped Two-Dimensional Semiconductors.
It is well-known that excitonic effects can dominate the optical properties of two-dimensional materials. These effects, however, can be substantially modified by doping free carriers. We investigateExpand

Temperature effect on optical spectra of monolayer molybdenum disulfide
Recently, measured optical absorption and photoluminescence spectra reveal substantial frequency shifts of both exciton and trion peaks as monolayer molybdenum disulfide, MoS2, is cooled from 363 KExpand

Theory-driven design of high-valence metal sites for water oxidation confirmed using in situ soft X-ray absorption.
The efficiency with which renewable fuels and feedstocks are synthesized from electrical sources is limited at present by the sluggish oxygen evolution reaction (OER) in pH-neutral media. We took theExpand
