| 55 | Abstract Electrons in solids behave as quantum waves, which may interact and interfere. The quantum electronic nature, which becomes important in reduced dimensionality and low temperatures, significantly influences properties such as electric conductivity, magneto-transport, and density of states. Our lab is interested in the interplay between geometry, dimensionality, disorder, and electronic properties of solid-state systems. Using advanced nano-fabrication techniques, high-precision electric measurements, and low-temperature techniques, we study the properties of different geometries such as ultrathin films, nanowires, granular films, and quantum dots, focusing on disordered metals, superconductors, and ferromagnets. The group’s areas of interest include disorder-induced superconductorinsulator-transition, transport through nanosystems and heterostructures of disordered systems, and single-layer graphene. We study the electric properties of different nanosystems in which the electrons feel a random potential and exhibit unique quantum behavior.
