Intervalley scattering by acoustic phonons in two-dimensional MoS2 revealed by double-resonance Raman spectroscopy
Autor: Bruno R. Carvalho, Yuanxi Wang, Sandro Mignuzzi, Debdulal Roy, Mauricio Terrones, Cristiano Fantini, Vincent H. Crespi, Leandro M. Malard, Marcos A. Pimenta
Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-8 (2017)
Double-resonance Raman scattering is a sensitive spectroscopic probe of the interplay between electrons and phonons in a crystal. Here, the authors unveil the signature of double-resonance intervalley scattering by acoustic phonons in two-dimensional

Quantification and Healing of Defects in Atomically Thin Molybdenum Disulfide: Beyond the Controlled Creation of Atomic Defects
Autor: Victor Carozo, Ana Laura Elías, He Liu, Mauricio Terrones, Zhong Lin, Tianyi Zhang, Ethan Kahn, Kazunori Fujisawa, Bruno R. Carvalho, Nestor Perea-Lopez, Sergio L. L. M. Ramos, Adam Bolotsky
Publikováno v: ACS Nano. 15:9658-9669
Atomically thin 2D materials provide an opportunity to investigate the atomic-scale details of defects introduced by particle irradiation. Once the atomic configuration of defects and their spatial distribution are revealed, the details of the mesosc

Electronic Band Tuning and Multivalley Raman Scattering in Monolayer Transition Metal Dichalcogenides at High Pressures
Autor: Luiz G. Pimenta Martins, Bruno R. Carvalho, Connor A. Occhialini, Natália P. Neme, Ji-Hoon Park, Qian Song, Pedro Venezuela, Mário S. C. Mazzoni, Matheus J. S. Matos, Jing Kong, Riccardo Comin
Publikováno v: Acs Nano, 16(5). AMER CHEMICAL SOC
Transition metal dichalcogenides (TMDs) possess spin-valley locking and spin-split K/K′ valleys, which have led to many fascinating physical phenomena. However, the electronic structure of TMDs also exhibits other conduction band minima with simila

Polarized Raman spectroscopy in low-symmetry 2D materials: angle-resolved experiments and complex number tensor elements
Autor: Bruno R. Carvalho, Geovani C. Resende, Marcos A. Pimenta, H. B. Ribeiro
Publikováno v: Physical chemistry chemical physics : PCCP. 23(48)
In this perspective review, we discuss the power of polarized Raman spectroscopy to study optically anisotropic 2D materials, belonging to the orthorhombic, monoclinic and triclinic crystal families. We start by showing that the polarization dependen
