Visible and Terahertz Nonlinear Responses in the Topological Noble Metal Dichalcogenide PdTe2
George J. de Coster, Lucas Lafeta, Stefan Heiserer +5
Nonlinear processes can offer pathways to next-generation sensors and frequency mixing devices to overcome modern imaging, detection, and communication challenges. In this article,…
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…
Van der Waals heterostructure metasurfaces: atomic-layer assembly of ultrathin optical cavities
Luca Sortino, Jonas Biechteler, Lucas Lafeta +5
Photonics has been revolutionized by breakthroughs in optical metasurfaces and layered two-dimensional materials. Yet, integrating these two fields in a singular system has remaine…
Excitonic Resonances in Coherent Anti-Stokes Raman Scattering from Single Wall Carbon Nanotubes
Georgy Gordeev, Lucas Lafeta, Benjamin Scott Flavel +2
In this work we investigate the role of exciton resonances in coherent anti-Stokes Raman scattering (er-CARS) in single walled carbon nanotubes (SWCNTs). We drive the nanotube syst…
Revealing Interfaces of Two-Dimensional Lateral Heterostructures by Second Harmonic Generation
Frederico B. Sousa, Lucas Lafeta, Alisson R. Cadore +2
The interface between two different semiconductors is crucial in determining the electronic properties at the heterojunction, therefore novel techniques that can probe these region…
Multimodal microscopy for characterization of amyloid-${\unicode[Times]{x3B2}}$ plaques biomarkers in animal model of Alzheimer's disease
Renan Cunha, Lucas Lafeta, Emerson A. Fonseca +5
Given the long subclinical stage of Alzheimer's disease (AD), the study of biomarkers is relevant both for early diagnosis and the fundamental understanding of the pathophysiology…
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…
Local photodoping in monolayer MoS2
Andreij C. Gadelha, Alisson R. Cadore, Lucas Lafeta +4
Inducing electrostatic doping in 2D materials by laser exposure (photodoping effect) is an exciting route to tune optoelectronic phenomena. However, there is a lack of investigatio…
Anomalous Non-linear Optical Response Of Graphene Near Phonon Resonances
Lucas Lafetá, Alisson Cardore, Thiago G. Mendes Sá +5
In this work we probe the third-order non-linear optical property of graphene, hexagonal boron nitride and their heterostructure by the use of coherent anti-Stokes Raman Spectrosco…
