Gerhard Ertl Lecture & Award

The Ertl Lecture Award was established in 2008 by the three Berlin universities (Humboldt University, Technical University and Free University) and the Fritz Haber Institute of the Max Planck Society and is awarded once a year. It commemorates former FHI Director Gerhard Ertl's Nobel Prize in Chemistry, which he received in 2007. The prize honours outstanding personalities and researchers in the field of catalysis where Ertl carried out exceptional research for many decades. The prize, sponsored by BASF, includes a one-week research stay at the participating Berlin institutions and a keynote lecture. The winner is typically announced in Spring, the lecture takes place around the December 10th, the anniversary of Ertl's Nobel Prize reception.

Joint seminar of Fritz Haber Institute and Institute for Molecular Science, Japan. Charge order (CO) has been recognized as one of the most important competing order in superconductive cuprates. In YBa₂Cu₃O_6+x (YBCO), CO could only be investigated by x-ray diffraction in under-doped YBCO with low critical temperatures (T_C), but not in highly-doped YBCO with high T_C suitable for device applications, due to the competing superconductive phase. Therefore, the most fundamental physical mechanisms governing CO, for example, the role of so-called charge reservoir (Cu-O chain) layers in CO and the spatial interplay of CO and SC, in highly-doped YBCO are still unclear.
