Partecipants: Department of Materials, ETH Zurich; CNRS, Aix-Marseille Université; Ecole Polytechnique, Université Paris-Saclay; Department of Physics “Tor Vergata”.

  1. Magnetism at low dimensionality (Individual Marie Curie COFUND Fellowship 2013-2016)

Partecipants: Department of Materials, ETH Zurich; Ecole Polytechnique Fédérale de Lausanne (EPFL), Lausanne; European Synchrotron Radiation Facility (ESRF).

 

Goal: Investigating magnetic relaxation at the atomic scale.

L.P. was awarded a highly competitive postdoctoral fellowship funded by ETH-Zurich and the Marie Curie Actions to explore atomic-scale structures for possible applications in computation and data-storage with the aim to demonstrate the use of single magnetic atoms on surfaces as qubits. As main proposer, he was allocated 5 beamtimes at ESRF between 2015 and 2017 to investigate these systems by x-ray absorption spectroscopy (XAS) and magnetic circular dichroism (XMCD) measurements which paralleled the in-house STM characterization. This work demonstrated, for the first time, that individual rare-earth atoms on ultra-thin insulating layers grown on non-magnetic metal substrates exhibit magnetic remanence and, therefore, are the first magnets formed by a single surface-adsorbed atom. In addition, these magnets have a record-high coercive field of 3.7 T, a magnetic lifetime of 1500 s at 10 K, and their hysteresis loop remains open up to 30 K. This first example of a single atom magnet shows bistability at a temperature which is significantly higher than the best single molecule magnets reported so far. Its extraordinary performances are achieved by a suitable combination of magnetic ground state and adsorption site symmetry, as well as by suppressing spin-electron scattering with conduction electrons by ultra-thin insulating layers.

Present research activity

Starting from March 2018, LP is a Researcher at the Department of Sciences of Roma Tre University, where his main research activity is related to the European Project „FLASH“. Within the project, LP is in charge of the growth by chemical vapor deposition (CVD) of SiGe heterostructures designed to work as active layers for Quantum Cascade Lasers. He is also responsible for the morphological and structural characterization of these materials. Within one of the FLASH workpackages, LP coordinates the combined efforts of the ROMA3 and ROMA1 units for the THz spectroscopic investigation of the grown materials together with the interpretation of their spectroscopic features via theoretical calculations. From a more general perspective, LP‘s research activity is focused at the moment on evaluating the impact of the CVD growth dynamics on the quality of heterointerfaces and how this quality affects the scattering channels of a cascade structure. Thanks to long-standing collaborations with research groups in Italy (A. Sgarlata at Roma „Tor Vergata“ and Luca Ottaviano in L‘Aquila) and abroad (I, Berbezier at CNRS, Marie Ingrid Richard at ESRF), LP is also working on fabrication and characterization of heteroepitaxial quantum dots, surface science of strained semiconductor systems and of epitaxial two-dimensional materials.

Research plans at short and mid term

LP’s research plans at short term are focused on developing designs and growth schemes for active-layer heterostructures suitable to achieve, first, electroluminescence fingerprints and, later on, gain in n-type Ge/SiGe quantum cascade structures. In particular, the next sixth months will be dedicated to extensive structural characterization obtained by scanning transmission electron microscopy (STEM), atomic probe tomography (APT) and X-ray diffraction of thick strain-symmetrized structures (up to 5 micron active region thickness) and heterointerfaces (featuring interface roughness below 0.2 nm), down to the ultrathin barrier limit (about 1 nm). By performing THz absorption spectroscopy measurements combined to theoretical modeling on different asymmetric coupled quantum well systems (with varying large-well width or barrier thickness), LP’s goal is to unambiguously demonstrate inter-well coupling and electron tunneling. By leveraging on the expertise acquired within the first year of FLASH, LP will develop simulations based on the Schroedinger-Poisson approach and energy-balance rate equation modeling for validating the tunneling barrier parameters and, in turn, to achieve a highly-controlled engineering of the electronic structure in forthcoming unipolar cascade systems based on n-type Ge/SiGe multi quantum-wells. Furthermore, LP will design pump-and-probe and time-domain THz spectroscopy experiments at the Free-Electron laser facility in Dresden to obtain information on non-radiative intersubband relaxation times in Ge/SiGe heterostructures. Parallel activity will focus on the atomic-scale scanning probe microscopy investigation of graphene on Ge, where, after having published the results obtained on Ge(001), LP is going to explore the graphene/Ge(110) interface. On this subject, a paper in collaboration with another research group in our department (A. Ruocco) is currently under submission. Additional work is at the moment being performed in collaboration with the Technical University of Denmark (DTU).

On a mid-term perspective, LP’s research goal is aimed at demonstrating room-temperature operation in group IV quantum cascade THz devices. The achievement of this milestone will pave the way to a next-generation of Si based THz sources on which, building on the expertise gained in FLASH, LP will have a strong competitive edge. This is expected to open novel research lines on the application of the quantum cascade laser technology (for example in THz spectroscopy or organic macromolecules and sensors) which will link LP’s activity with other groups in our department.

Indeed, one of the main goal of LP is to actively integrate his activity with other research lines in the Nanoscience section and overall in the Department of sciences of Roma Tre. To pursue this goal, starting from the beginning of his stay, LP is participating to the Call4Ideas project “Produzione di superfici nanostrutturate e biocompatibili per la generazione di tessuto cartilagineo in vitro” which gathers together the materials science, biology and chemistry research lines of our department. Within the Call4Ides framework, LP is contributing to the design and writing of a proposal for a European FET project to be submitted in the September 2019 call. To this end, he will leverage on the expertise gained in previous successful European project proposals (individual Marie Curie and FLASH FET). LP’s objective is to combine his skills on surface characterization at the nanoscale as well as on nano and meso-scale patterning with that of the other proponents in the department for disentangling the effects on osteogenic differentiation of mechanical stimuli (induced for example by nanopatterning) from that of osteogenic supplements in culture media.
