Single-electron manipulations

This work focuses on single-electron manipulations, particularly the ability to switch the charge states of adsorbed atoms and molecules through combined atomic force microscopy (AFM) and scanning tunneling microscopy (STM) techniques. We also investigate the dynamics of single electrons (polarons), in ionic crystals using AFM and Kelvin probe microscopy, which allows us to observe and control electron behavior at the atomic level. These studies contribute to our understanding of charge dynamics in nanoscale systems, with potential applications in electronic devices.

Complex materials, perovskites

This research focuses on the surface science of complex materials, including ternary compounds and layered structures, with an emphasis on cleaved single crystals. Our primary materials of interest are perovskite oxides, particularly titanates, tantalates, and niobates, as well as organohalide perovskites. We also investigate surfaces with uncompensated polarity, such as mica, and scintillating materials like europium-doped sodium iodide (NaI). Additionally, we remain open to exploring other materials with intriguing surface properties that may contribute to our understanding of complex systems.

Silicon surfaces

We examines the interaction of single atoms and molecules with silicon substrates, focusing on how these entities can assemble into nanostructures such as quantum dots and quantum wires. We also study the kinetics of atomic processes on these surfaces through computer simulations, which provide insights into the fundamental behaviors and potential applications of these nanostructures in various technologies.

Organic molecules

We study the interaction of organic molecules with various substrates, with a particular interest in two-dimensional crystals of organic molecules. This research aims to understand how molecular organization and substrate interactions influence the properties and potential applications of these organic 2D crystal structures.
