Research Interests
With the advent of novel and nanoscale materials, materials research is expected to play an increasing role in sustainable technologies for nanolectronics and energy conversion, storage and savings. However, incremental improvements in most of these areas are not sufficient to address the important issues of durability, efficiency and costs. Research is therefore needed to develop materials with new functionalities. Research in the Iavarone group is focused on the electronic properties of quantum materials. The main objective is a fundamental understanding for the functionalization of their electronic ground states. Our team studies materials like superconductors, topological materials, transition metal dichalcogenides, 2D materials and their heterostructures. In artificially fabricated heterostructures the controlled confinement and interaction of correlated states can be tuned and has the potential to lead to novel quantum phenomena useful to address important technological problems.
The lab revolves around the use of low temperature scanning tunneling microscopy and spectroscopy and other scanning probe techniques to investigate the properties of materials at the nanoscale and visualize emergent phenomena.
