Vanadium doping induced valley asymmetries in WS monolayers
Frederico B. Sousa, Boyang Zheng, Elizabeth Grace Houser +10
Transition metal dichalcogenide (TMD) monolayers offer an innovative platform for encoding and manipulating information through the valley degree of freedom. While unique valley-re…
Resonance-Enhanced Four-Wave Mixing Imaging for Mapping Defect Regions in Vanadium-Doped WS2 Monolayers
Felipe Menescal, Frederico B. Sousa Mingzu Liu, Ana P. M. Barboza +8
Defect engineering is crucial for tuning 2D transition metal dichalcogenide properties for quantum and optoelectronic applications. While conventional photoluminescence (PL) and Ra…
Multi Moire Networks in Engineered Lateral Hetero-Bilayers: Programmable Phononic Reconfiguration and Second Harmonic Generation
Suman Kumar Chakraborty, Frederico B. Sousa, Chakradhar Sahoo +14
Moire engineering in two-dimensional transition metal dichalcogenides enables access to correlated quantum phenomena. Realizing such effects demands simultaneous control over twist…
Strong magneto-optical responses of an ensemble of defect-bound excitons in ambient exposed WS and WSe monolayers
Frederico B. Sousa, Alessandra Ames, Mingzu Liu +8
Transition metal dichalcogenide (TMD) monolayers present a singular coupling in their spin and valley degrees of freedom. Moreover, by applying an external magnetic field it is pos…
Effects of Vanadium Doping on the Optical Response and Electronic Structure of WS Monolayers
Frederico B. Sousa, Boyang Zheng, Mingzu Liu +6
Two-dimensional dilute magnetic semiconductors has been recently reported in semiconducting transition metal dichalcogenides by the introduction of spin-polarized transition metal…
Amplification of interlayer exciton emission in twisted WSe/WSe/MoSe heterotrilayers
Chirag C. Palekar, Paulo E. Faria Junior, Barbara Rosa +4
Transition metal dichalcogenide (TMDC) heterostructures have unique properties that depend on the twisting angle and stacking order of two or more monolayers. However, their practi…
