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…
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…
Probing Noncentrosymmetric 2D Materials by Fourier Space Second Harmonic Imaging
Lucas Lafeta, Sean Hartmann, Bárbara Rosa +3
The controlled assembly of twisted 2D structures requires precise determination of the crystal orientation of their component layers. In the established procedure, the second-harmo…
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…
