Abstract

This project aims to nucleate a research group on optical properties of individual light emitters studied with high spatial and spectral resolution by Scanning Tunnelling Microscopy (STM) in association with a high performance optical system. In this system, local luminescence signals generated by the STM tunnelling current will be employed to study semiconductor nanostructures with sub-nanometer spatial resolution. The objectives of this proposal are the development of a unique instrumental setup in the state-of-the-art and explore its potential. Thus, this project will contribute to the understanding of optical properties of new materials, such as III-V nanowires, C-Dots, bidimensional semiconductors (MoS2, BN, etc), among others. (AU)
