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…
Ultrafast melting and recovery of collective order in the excitonic insulator TaNiSe
Hope M. Bretscher, Paolo Andrich, Prachi Telang +4
The layered chalcogenide TaNiSe has been proposed to host an excitonic condensate in its ground state, a phase that could offer a unique platform to study and manipulat…
Imaging the coherent propagation of collective modes in the excitonic insulator candidate TaNiSe at room temperature
Hope M. Bretscher, Paolo Andrich, Yuta Murakami +10
Excitonic insulators host a condensate of electron-hole pairs at equilibrium, giving rise to collective many-body effects. Although several materials have emerged as excitonic insu…
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…
