Spintronics

The remarkable trend in electronics described by the Moore law is today experiencing increasing difficulties due to fundamental limitations in the current miniaturization approach. Alternative strategies need to be developed, e.g. exploiting a bottom-up molecular approach, mesoscopic devices, additional degrees of freedom or quantum physics. In this frame, spin is likely going to play a crucial role to carry classical or quantum information. Spintronics research in Lecce addresses different fields, from nanoscale devices based on magnetic molecules or nanoparticles to magnetic multilayers and more recent activities on RF systems for hybrid spintronics. Furthermore, we also investigate novel materials (such as multiferroics and functional oxides) and perform magnetic and ferroelectric characterizations. More in detail:

NanoElectronics/Spintronics

This research was the starting point for the group, thanks to the EU project SpiDME. To interconnect the individual building blocks at the nanoscale, we employ electron beam lithography (EBL), focused ion beam or a non- conventional method based on the selective wet-etching and oxidation of an AlGaAs/GaAs quantum well structure for the simultaneous fabrication of large arrays of nanodevices. Molecules or nanoparticles are typically positioned by specific immobilization procedures exploiting suitable functional end-groups. Charge and spin transport studies are carried out within superconducting magnets up to 10.5T and down to 10 mK.

Nanomagnetism

Nanomagnetism in magnetic materials and nanoparticles is investigated by vibrating sample magnetometry and a.c. susceptibility. Beyond hysteresis, both zero-field cooled and field cooled curves are typically acquired to evaluate the blocking temperature.

Magnetic Multilayers

Multilayer structures are the basis for giant or tunneling magnetoresistance devices. Our research focuses on the integration of further layers including nanoparticles, magnetic molecules, multiferroics or superconducting films. On the technological side, the target is to achieve a large magnetoresistance, which is useful for further applications such as in biosensors.

RF systems for hybrid spintronics

Recently, we started to investigate 3D microwave cavities and SAW devices for their integration in hybrid spintronic architectures where photons and phonons are coupled to the magnetic degree of freedom.

Multiferroics and Functional Oxides

Here we investigate high-k materials for gate stack technology in logic and memory devices and multiferroic materials for implementing novel operational concepts in spintronics exploting magnetoelectric coupling. Structural, morphological and dielectrical characterizations are typically carried out, while ferroelectric and multiferroic properties are investigated by means of PFM, KPFM, Dielectric and Ferroelectric (PUND) measurements.

EIT RawMaterials Roadshow

21 giugno 2019 ore 09:00 – 15:00

   

Lecce, Aula Fermi Edificio Aldo Romano, Campus Ekotecne, Via Lecce-Monteroni

   

Farà tappa a Lecce il prossimo 21 giugno, presso l’Aula Fermi dell’edificio IBIL all’interno del Campus Ecotekne, l’EIT RawMaterials, la piattaforma per il sostegno all’innovazione finanziata dall’Istituto Europeo di Innovazione e Tecnologia (EIT).

   

L’EIT ha creato le cosiddette KIC – Knowledge Innovation Community, comunità che mirano alla promozione dell’innovazione e della formazione in Europa in settori cruciali, sostenendo l’imprenditorialità e favorendo il passaggio di nuove idee dalla fase di incubazione al mercato.

 

La EIT RawMaterials si impegna ad affrontare la sfida globale dell’approvvigionamento delle materie prime in Europa attraverso programmi e progetti che mirano allo sviluppo di tecnologia nell’intera catena di valore delle materie prime: dall’esplorazione delle risorse, all’industria mineraria, dai processi metallurgici alla sostituzione delle materie prime critiche o tossiche, dal riciclo dei materiali dei prodotti a fine vita sino alla progettazione di prodotti per l’economia circolare. Nell’ambito dei programmi di sviluppo a livello regionale, la EIT RawMaterials ha creato un Hub nella Regione Puglia coordinato da ENEA, al fine di incrementare il coinvolgimento degli ecosistemi locali nelle attività della KIC e del suo partenariato.

 

Il MedinHub avrà inoltre l’obiettivo di raggiungere nuove organizzazioni e promuovere la partecipazione delle industrie e delle PMI più innovative, nonché il coinvolgimento delle prestigiose università e centri di ricerca dell’area.
