INMA Impulso: Sven Barth
INMA Impulso seminar: “Precursors for direct-write nanofabrication with electrons and ions”
On Thursday 31 August will take place a new INMA Impulso seminar, a series of conferences organized by the Instituto de Nanociencia y Materiales de Aragón (INMA), a joint institute of the CSIC and the University of Zaragoza, which seeks to bring the most cutting-edge research to society.
On this occasion, Sven Barth from the Goethe Institute of Physics of the University of Frankfurt will give a session entitled: “Precursors for direct-write nanofabrication with electrons and ions”.
The session will take place on Thursday 31 August at 12:00 h in the Conference Room of the Edificio I+D+i, Río Ebro Campus, University of Zaragoza.
Summary: Focused electron beam deposition (FEBID) allows the spatially controlled formation of nanoarchitectures on a wide range of substrate materials. The composition and purity of the as-grown material can be tailored by specific precursor development, which provides a chemical impetus for advances in this field. Based on the knowledge gained by surface science studies, several different reaction paths could be assigned according to the composition gained in FEBID experiments. The talk will briefly summarize the state-of the art of precursors used and introduce new single-source precursors.
Moreover, specific effects of writing strategies, e.g., serpentine vs. spot deposition, in FEBID and comparison between FEBID/FIBID in the as-deposited materials properties will be discussed. The majority of the talk will be focused on heterometallic precursors.
The talk will illustrate the unique opportunities of these more complex precusors in terms of fundamental lessons learned as well as their applicability for the direct writing of functional materials.
In addition, new approaches based on FEBID nanostructures, such as 3D nano-micro- CVD and a new, controlled phase separation on the nanoscale, will be presented.
La sesión tendrá lugar el jueves 31 de agosto a las 12:00 h en la Sala de Conferencias del Edificio I+D+i del Campus Río Ebro de la Universidad de Zaragoza.
