The Unit is active in the investigation of transport properties of advanced materials and devices through noise spectroscopy. The spectral analysis of low frequency noise (noise spectroscopy) is a powerful tool to study the properties of these materials, as it highlights the sources of intrinsic fluctuation of the transport properties, allowing to shed light on the basic mechanisms at work and also to set the ultimate limits of achievable performance of devices made from such materials. The investigated systems comprise:

 

●       2D gas nano-sensors and electron gas interfaces;

 

●       green electronics materials;

 

●       high Tc superconductors;

 

●       manganites;

 

●       solar cells (crystalline, polymeric, perovskites);

 

●       carbon nanotube composites;

 

●       metals.

 

 

Other research areas covered by the researchers of the unit are the development of innovative superconductive devices, based on superconducting nanostructures and on Josephson junctions for the realization of single photon detectors in the visible, IR and microwave spectral regions and related superconducting electronics. The applications of such superconducting devices are:

 

●       Fast optical interfaces for superconducting digital circuits;

 

●       Secure optical telecommunications (quantum key distribution);

 

●       Qubit  interfacing.

 

●       Quantum sensing

 

 

 

●       Closed cycle low temperature noise test station (10 to 300 K)

 

 

●       Closed cycle ultra-low temperature test station (0.3 to 300 K)

 

 

●       Continuous flow optical cryostat (3 to 300 K)

 

●       Test camera for room temperature electronics (-40 to 120 °C)
