INAUGURAL LECTURE PROF. GUUS RIJNDERS

On Thursday March 31, 2011 Guus Rijnders has given his inaugural lecture called:

NANOMATERIALEN INZICHT (INSIGHT NANOMATERIALS)

Prof. dr. ing. A.J.H.M. (Guus) Rijnders (1964) finished his PhD on “Initial growth of complex oxides: study and manipulation“, with supervisors: prof. dr. Horst Rogalla and prof. dr.ing. Dave H.A. Blank. On April 1, 2010 he became professor in NanoElectronic Materials Science in the Inorganic Materials Science group (IMS). Since January 2011 he is chairman of IMS.

Guus research focuses on the structure-property relation of complex materials, especially ceramic oxides. This class of materials includes, amongst others, ferroelectric, ferromagnetic, superconducting, high-K dielectric, mixed ionic-electronic conducting and transparent conducting oxides. During the last decade, his research has contributed significantly to the progress in the controlled growth of epitaxial (complex) oxide thin films as well as the understanding of their properties. To name a few, these are: substrate treatment to obtain single terminated surfaces, atomic level control of the growth, as well as growth manipulation. For the growth studies, custom-made pulsed laser deposition systems were developed. During his PhD work, he developed the first time-resolved RHEED-system operating in-situ during deposition at high pressures up to 100 Pa. With these systems several new growth phenomena have been observed, leading to new proposals to manipulate the growth behaviour of complex materials, like pulsed laser interval deposition. RHEED controlled PLD is used to study and realize block-by-block (or sub-unit cell) deposition of complex materials. The systems are now commercial available (Twente Solid State Technology) and a number of systems are operational in leading laboratories.

Current research includes the growth and study of artificial materials and the realization of novel (nanoscale) devices thereof. This research includes (multi)ferroelectrics and piezoelectrics, and correlated electron systems at oxide interfaces.

In 2006 he was awarded with a VIDI grant of the Dutch Science Foundation (NWO) for his work on amazing electronic effect at oxide interfaces. He is Captain of the Nano-electronic Materials flagship within the NANONED program and Program Director of NanoNextNL. Leader of the PiezoMEMS cluster of the SmartPIE programme, funded by the participating companies and universities and by the Dutch government through the SmartMix program and member of the board of Applied Piezo foundation, with the aim to facilitate the access of industry to utilize piezo technology.
