LNLS researcher receives award for best doctoral thesis


The prize is awarded to theses that have contributed significantly to the advancement of knowledge of nature and its properties.

LNLS researcher Ingrid David Barcelos was awarded by the Brazilian Society of Physics (SBF) with the “Professor José Leite Lopes Award for Best Doctoral Thesis of 2015” for her thesis entitled “Study of structural and optical properties of heterostructures formed by two-dimensional materials “.

Ingrid investigated the production of heterogeneous structures formed by two two-dimensional materials – graphene and hexagonal boron nitride (hBN). Her Ph.D. work was based on the study of the interactions and structural and optical properties of these materials, and the results show that it is possible to integrate them into systems with well-defined interfaces.

According to Ingrid, the creation of artificial materials, which combine various individual physical properties of each compound, make innovative applications possible. This approach allows the creation, for example, of new electronic devices that can perform several mechanical, electronic and optical functions simultaneously. “It is already possible to identify key areas where this type of approach will be important, such as ultra-strong nano-composite materials, electromechanical devices and for the production of more efficient solar cells.”

The SBF award is granted to theses that contain original results that have contributed significantly to the advancement of knowledge of nature and its properties. This year, 11 works from the areas of Theoretical and Experimental Physics, with theses defended in the period of 2014-2015, competed for the award.

Ingrid, who is part of the Infrared Nanospectroscopy group at LNLS, was the second woman to win the SBF award. Her thesis was supervised by Prof. Ângelo Malachias de Souza, from the Physics Department of the Federal University of Minas Gerais (UFMG), in Brazil.
