ABSTRACT
The current rise of nanotechnology and nanoscience has been followed by constant advances in surface science techniques. Nowadays, we can routinely see individual atoms and molecules and probe the momentum and energy of valence electrons which define many of the electronic and thermal properties of materials, among others. During this talk, we will review several surface science techniques. We will start with microscopy techniques that allow us to see atoms and molecules in real space, such as scanning tunneling microscope, STM, and non-contact atomic force microscopy, Nc-AFM. Next, we will move on to spectroscopy techniques that allow us to probe the electronic structure of materials, such as X-ray photoelectron spectroscopy and angle-resolved photoelectron spectroscopy. After discussing some of my works on molecular self-assembly and graphene, we will investigate how molecular self-assembly could be used to overcome some of the present challenges to incorporate graphene into next-generation electronic devices.
