Abstract

The collaboration between Brazilian partners and researchers from the Institute of Nanoscience and Engineering at the University of Arkansas (NanoUark) has been established for twenty years. With Prof. Greg Salamo, we have published about 50 papers in three book chapters in indexed scientific journals and facilitated the exchange of eight Brazilian students and postdoctoral researchers during this period. NanoUark has an epitaxial growth laboratory with the capability to grow various types of materials, and more recently, it has been dedicated to the epitaxial growth of two-dimensional materials (GaSe and GeSe) using molecular beam epitaxy (MBE) techniques and group IV compounds like SiGeSn. These materials have potential applications in photonics, such as quantum emitters and photosensors in the visible and infrared regions. In recent years, the laboratories of IFSC and UFSCar have been dedicated to the processing and characterization of photonic materials, participating in multi-user projects (22/10340-2 and 22/11526-2) that will further enhance research in these areas with potential applications in nanophotonics. In 2020, we initiated collaboration with Prof. Andras Kis's group (EPFL - Switzerland) to study intense interaction regimes between 2D materials, specifically MoS2 and WS2 (obtained through exfoliation), and plasmonic metasurfaces. This collaboration resulted in the proposal to which this is linked (21/03311-03), aiming to encompass other materials with similar optical properties. (AU)
