Chemical treatments of Monolayer Transition Metal Dichalcogenides and Their Prospect in Optoelectronic Applications
Zhaojun Li, Hope Bretscher, Akshay Rao
The interest in obtaining high-quality monolayer transition metal dichalcogenides (TMDs) for optoelectronic device applications has been growing dramatically. However, the prevalen…
Photophysical comparison of liquid and mechanically exfoliated WS monolayers
Zhaojun Li, Farnia Rashvand, Hope Bretscher +4
Semiconducting transition metal dichalcogenides (TMDs) are desired as active materials in optoelectronic devices due to their strong excitonic effects. They can be exfoliated from…
Mechanistic Insight to the Chemical Treatments of Monolayer Transition Metal Disulfides for Photoluminescence Enhancement
Zhaojun Li, Hope Bretscher, Yunwei Zhang +5
There is a growing interest in obtaining high quality monolayer transition metal disulfides (TMDSs) for optoelectronic device applications. Surface chemical treatments using a rang…
Giant Photoluminescence Enhancement in MoSe monolayers treated with Oleic Acid Ligands
Arelo O. A Tanoh, Jack Alexander-Webber, Ye Fan +6
The inherently low photoluminescence (PL) yields in as prepared transition metal dichalcogenide (TMD) monolayers are broadly accepted to be the result of atomic vacancies (i.e. def…
The bright side of defects in MoS and WS and a generalizable chemical treatment protocol for defect passivation
Hope M. Bretscher, Zhaojun Li, James Xiao +12
Structural defects are widely regarded as detrimental to the optoelectronic properties of monolayer transition metal dichalcogenides, leading to concerted efforts to eliminate defe…
