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…
Nonselective generalized measurements as a resource for quantum thermal machines in a double quantum dot
Bruno Carvalho, Jonas F. G. Santos, Moises Rojas
We investigated quantum thermal machines powered by sequential nonselective generalized measurements, taking a double quantum dot with coherent interdot tunneling as a working subs…
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…
A Universal Raman Spectroscopic Framework for Defect Quantification in Mono-to-Multilayer Graphenic Materials: The Graphene Atlas
Kazunori Fujisawa, Bruno R. Carvalho, Pedro Venezuela +4
Point defects, though atomically small, significantly influence the properties of 2D materials. A general method for characterizing point defect density () in graphenic ma…
Second- and third-order optical susceptibilities in bidimensional semiconductors near excitons states
Lucas Lafeta, Aurea Corradi, Tianyi Zhang +6
Semiconducting Transition Metal Dichalcogenides (TMDs) have significant nonlinear optical effects. In this work we have used second-harmonic generation (SHG) and the four-wave mixi…
Nonlinear dark-field imaging of 1D defects in monolayer dichalcogenides
Bruno R. Carvalho, Yuanxi Wang, Kazunori Fujisawa +10
Extended defects with one dimensionality smaller than that of the host, such as 2D grain boundaries in 3D materials or 1D grain boundaries in 2D materials, can be particularly dama…
Strong exciton regulation of Raman scattering in monolayer dichalcogenides
Yuanxi Wang, Bruno R. Carvalho, Vincent H. Crespi
The weakly screened electron-hole interactions in an atomically thin semiconductor not only downshift its excitation spectrum from a quasiparticle one, but also redistribute excita…
