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…
Anisotropic Dopant and Strain Architectures in WS Nanocrystals Driven by Growth Kinetics
Frederico B. Sousa, Raphaela de Oliveira, Matheus J. S. Matos +11
Dopant distribution in two-dimensional semiconductors is typically assumed to be stochastic, limiting deterministic defect engineering. Here, we show that non-equilibrium growth ki…
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…
Nano-optical investigation of grain boundaries, strain and edges in CVD grown MoS monolayers
Frederico B. Sousa, Rafael Battistella Nadas, Rafael Martins +6
The role of defects in two-dimensional semiconductors and how they affect the intrinsic properties of these materials have been a wide researched topic over the past decades. Optic…
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…
