Activity B: Superconducting and correlated low dimensional materials and devices for quantum electronics and spintronics

Activity2This project focuses on the physics of low dimensional materials and of superconducting devices in quantum technologies, with particular attention to the fields of quantum electronics and spintronics. The researchers involved in the project are expert in fabrication of materials and devices as well as their characterization employing both low-temperature magneto-transport measurements, and advanced spectroscopies. Theoretical activities are focused to prediction of novel phenomena and interpretation of experimental measurements.

Activity Leader: Procolo Lucignano

State of art
Low dimensional systems, like graphene, topological insulators, Van der Waals atomic crystals, unconventional and low dimensional superconductors, oxide interfaces exhibiting two dimensional electron gases, are coming out as leading topics in condensed matter physics. The complex electronic states generated at the surfaces and interfaces of these materials are the ideal playground for the study of new quantum phenomena and new phases of matter, where quantum coherence can play an important role up to the macroscopic scale. This is expected to provide yet unpredictable outcomes for the science and technology of next decades and to open new directions in micro-nano electronics, spintronics and superconducting electronics, enabling the development of devices based on novel, more powerful, logic schemes to increase computing power and to reduce energy consumption.


The activities planned will provide unique opportunities to investigate fundamental physical phenomena, generate novel functionalities and to manipulate them either by applying external stimuli, as magnetic/electric fields, (spin-polarized) currents and light, or resorting to atomic layer engineering and acting on them across an interface with different materials through epitaxial strain, spin-orbital coupling, exchange bias, superconducting, magnetic proximity effect and so on.

Main topics:

  • Superconducting/ferromagnetic proximized heterostructures, Josephson devices, and hybrid systems
  • Novel 2D systems (such as graphene, topological insulators, BiSe, BiTe, LAO/STO, ZnO/ZnMgO and variants
  • Artificial transition metal heterostructures for novel 2D-superconductivity and magnetism
  • Growth of low-dimensional systems with atomic-level control supported by real-time/in-situ monitoring
  • 2D Electron gases and spin polarized electron gases in oxides and other novel materials
  • X-ray spectroscopies at large scale facilities on low dimensional superconductors and complex heterostructures
  • Advanced surface and interface spectroscopies in novel materials and devices: atomistic simulations and experiments
  • Low-Temperature Transport and quantum effects in (nano)devices and interfaces based on superconducting, topological and other novel materials
  • Spin injection and spin imbalance in superconducting heterostructures
  • Bose-Einstein condensation of excitons and exciton polaritons
  • Exciton-mediated superconductivity
  • Novel platforms for topological effects based on compact three-dimensional curved nanoarchitectures.
