Rainer Waser

from Wikipedia, the free encyclopedia

Rainer Martin Waser (born September 16, 1955 in Frankfurt am Main ) is a German physical chemist.

Live and act

Waser studied chemistry from 1974 with a focus on physical chemistry at the TH Darmstadt and graduated in 1979 with a diploma. He then worked in the electrochemistry department at the University of Southampton in 1979/80 and received his doctorate in Darmstadt under Konrad Georg Weil ( studies on the formation of mobility of surface complexes at the silver / electrolyte interface ). He then worked at Philips Research in Aachen in the ceramics for electronics department.

In 1992 Waser was appointed full professor for electronic materials at RWTH Aachen University. In addition, he took over as director of the electronic materials department at the Peter Grünberg Institute at Forschungszentrum Jülich . There he was the founder of the Center of Nanoelectronic Systems for Information Technology (CNI) in 2003 . From 2004 to 2008 Waser was also an adjunct professor at Jiaotong University in China.

Waser founded the Fundamentals of Future Information Technology section of the Jülich-Aachen Research Alliance (JARA-FIT) in 2007 . Since 2010 he has been the spokesman for the Fundamentals of Future Information Technology research program of the Helmholtz Association . One year later he became the deputy spokesman for the SFB Nanoswitch and has been professor spokesman for the Faculty of Electrical Engineering and Information Technology at RWTH Aachen University since 2012.

Waser deals with ferroelectrics and ferroelectric thin films, in particular he is known for revitalizing the field of resistive switches as storage elements in information technology ( memristors ). These can be switched with less energy than conventional electronic components. In 2006 he clarified the basic mechanism for their switching properties.
