Abstract

In this scientific initiation project, a detailed experimental study will be carried out on the fabrication and subsequent s-SNOM characterization of 2Ds heterostructures based on lamellar materials (h-BN, MoO3 and Talc) as well as on their lithography in the form of resonators. The fabrication and assembly of the nanostructures will be carried out in the Laboratory of Bidimensional Materials (L2D) in line with the s-SNOM instrumentation in operation on the IMBUIA line of Sirius. Eventually, more sophisticated structures will be produced via nano-thinning by "Focused Ion Beam" (FIB) at the Laboratory of Micrometric Samples (LAM) at the National Synchrotron Light Laboratory (LNLS).
