Running projects

COST action CM1301 on Chemistry for Electron-Induced Nanofabrication (CELINA). The project aims at the study of new gas precursors for focused electron beam-induced deposition (FEBID) nanolithography.

Biographical sketch

Coordinator of S3 Nanofabrication Laboratory, an open facility equipped with a Dual Beam FIB-SEM and an EBL system.
Primary research interests are about the nanofabrication by focused ion and electron beams. Within FIB nanolithography field, the main topics include: nanofabrication of holographic plates and slits for electron interference experiments, nanopatterning of surfaces and thin films for nanomagnetism and nanotribology studies, fabrication of nanogap electrodes and manganite spintronic devices, scanning probe tips modification. Regarding electron-beam nanofabrication, the key topic is focused electron beam-induced deposition (FEBID) of nanowires from metal, insulating and magnetic gas precursors, characterized from a structural and electrical viewpoint.
Also involved in materials science research requiring FIB preparation methods (e.g. for TEM analysis), and FIB-SEM cross-section analysis. These latter topics, along with circuit and device edit, are also the core of a busy service activity performed for companies and external scientific users.
Research activity before entering S3 center (2003) was focused onto the physical processes at the basis of electron diffraction inside crystalline surfaces and thin films and on the structural characterization of ultrathin epitaxial films of magnetic elements.
Author of 80 publications on international journals, 3 book chapters, 1 national patent, has an H-index (ISI) of 16.
