Seminários do Departamento de Física dos Sólidos – Victor Carozo (PUC-Rio)

19 de septiembre de 2023-10:50 AM - 12:00 PM

Synthesis and optical properties of two-dimensional materials Victor Carozo (PUC-Rio) Resumo: Two-dimensional materials have recently emerged as a captivating class of new crystals, offering exceptional properties and immense potential for diverse technological applications. This study delves into the synthesis and optical analysis of these materials, with a specific emphasis on the application of Raman spectroscopy and second harmonic generation (SHG) to elucidate their unique optical attributes. The synthesis of two-dimensional materials, encompassing transition metal dichalcogenides (TMDs), and other layered materials, constitutes a central aspect of this investigation. The controlled fabrication of high-quality two-dimensional layers is pivotal for harnessing their inherent optical characteristics, employing methods such as chemical vapor deposition (CVD) and vapor phase deposition (VPD) to tailor their composition and structure. Raman spectroscopy emerges as an invaluable tool for the comprehensive characterization of two-dimensional materials, enabling insights into layer thickness, defects, strain, and interlayer interactions. Additionally, it facilitates non-destructive examinations of their electronic and lattice properties, facilitating precise material identification and quality assessment. Furthermore, the study explores the second harmonic generation (SHG) properties of two-dimensional materials, shedding light on their structural asymmetry, electronic band structures, and potential applications in nonlinear optics and optoelectronics. This seminar highlights the increasing importance of two-dimensional materials in the field of physics and materials science. It underscores the roles played by Raman spectroscopy and SHG in advancing our comprehension of the synthesis and optical characteristics of these materials. These insights provide a solid foundation for the development of devices and applications centered on two-dimensional materials, […]
