Biography

Dr Ludovic Rapp is a Research Fellow at Laser Physics Centre (LPC) at the Australian National University (ANU). Ludovic has a strong background in ultra-fast laser interaction with matter, ultra-fast micromachining and expertise in beam shaping. His research work at ANU developing an ultrafast laser induced confined microexplosion method led to the discovery of two new high-density phases of Silicon, published in Nature Communications with his name as a first author. His research interest also includes nanostructures, chemistry, as well as crystallography. He has strong experimental and multidisciplinary skills such as material analysis techniques (SEM, TEM, FIB, AFM and Raman spectroscopy). Ludovic won a number of competitive funding such as the ARC Discovery Grant in 2017, the Endeavour Research Fellowship from Australian Government in 2011 and the Scientific Mobility Program by the Embassy of France in Australia in 2013, and was awarded a PhD thesis prize by the Mediterranean University of France in 2011.

    Experimental evidence of new tetragonal polymorphs of silicon formed through ultrafast laser induced confined micro explosion

    Nature Communication 6:7555 (2015) 

    http://dx.doi.org/10.1038/ncomms8555


    A recent study demonstrating the formation of two novel metastable Si phases by the ultrafast laser induced confined microexplosion method, predicted theoretically but never observed in nature or in laboratory experiments. Theoretical prediction of four more new Si-allotropes with 32 atoms in a primitive cell, two tetragonal and two monoclinical.
