Effects of Reduced Interlayer Interactions on the K-point Excitons of MoS Nanoscrolls
Sagnik Chatterjee, Tamaghna Chowdhury, Pablo Díaz Núñez +6
Transition metal dichalcogenide (TMD) nanoscrolls (NS) exhibit significant photoluminescence (PL) signals despite their multilayer structure, which cannot be explained by the strai…
Tensile strain induced brightening of momentum forbidden dark exciton in WS
Tamaghna Chowdhury, Sagnik Chatterjee, Dibyasankar Das +8
Transition-metal dichalcogenides (TMDs) host tightly bound quasi-particles called excitons. Based on spin and momentum selection rules, these excitons can be either optically brigh…
Modulation of trion and exciton formation in monolayer WS2 by dielectric and substrate engineering
Tamaghna Chowdhury, Diptabrata Paul, Divya Nechiyil +5
Photoluminescence (PL) of transition metal dichalcogenide (TMD) monolayers is strongly influenced by the dielectric environment. The defect states present in the substrate induces…
Optoelectronic characterisation of twisted germanium sulfide nanowires with experimental observation of intrinsic ferroelectricity
Tamaghna Chowdhury, Aastha Vasdev, Goutam Sheet +1
We report the optoelectrical characterisation of Eshelby twisted Germanium sulfide (GeS) nanowires with first experimental observation of ferroelectric order at room temperature in…
