Abstract Electronic properties of low dimensional systems 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, has a significant influence on properties such as electric conductivity, magneto-transport and density of states. Our lab isinterested 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. Currently the group’s areas of interest include the disorder induced superconductor- insulator-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.
