Brief profile

Currently, Eugeniu is employed as a Research Fellow in the ARC Centre of Excellence for Coherent X-ray Science (CXS). His role is mainly to provide his colleagues with test samples and samples of interest, so they can assess the degree of certainty of specific set of experiments and methods, which is of high importance for providing high degree of research and scientific output. This also involves the development of new fabrication methods and characterization of various samples. Within his role, he is interested in development of new generation of high-efficiency Fresnel Zone Plate for X-Ray optics.

Eugeniu completed a Ph.D. in Materials Science and Engineering (2007) at Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany). His doctoral thesis “Organically-modified semiconductor surfaces: from electron-beam induced modification to wettability control” involved the investigation of a new class of materials (self-assembled monolayers) on semiconductor surfaces. This is a novel area were organic molecules are adsorbed to semiconductor surfaces. He has studied the possibility of patterning such surfaces by means of electrons and metallization. Additionally, he has explored the possibility of modifying titanium oxide surface characteristics by various methods: chemical functionalization and geometrical alteration of titanium oxide surface, and UV-light induced modification of its wetting properties.
