Welcome to the Helmholtz-Zentrum Berlin

At the Helmholtz Zentrum Berlin für Materialien und Energie (HZB), we conduct research on complex systems of materials that contributes to dealing with challenges such as the energy transition. The HZB research portfolio includes solar cells, solar fuels, thermoelectric, and the materials with which you can construct new, energy-efficient information technologies such as spintronics. Research on these energy materials is closely connected with the operation and advanced development of the BESSY II photon source. And our research approach always concentrates on thin-film technologies. Find out more at this About us.

    Summer in the lab

    22 students from all over the world are working at HZB for eight weeks

    The summer programme of HZB has a good reputation among students, and every year HZB receives a lot more applications than it can fund. Now, 22 young people have come from 15 different countries to start their research project in a HZB team. They will present their results at the end of September.  [...].

    New model for bimolecular reactions in nanoreactors

    A group of theoretical physicists have devised a mathematical model of two different molecules reacting within so called nanoreactors that act as catalysts. They gained surprising new insights as to what factors promote reactions and how to control and select them. The model is relevant for a wide range of research fields, from biophysics to energy materials. [...].

    User research at BER II: Lupin roots observed in the act of catching water from soil – so far too quick for 3D views

    Lupins not only produce colourful blossoms but also nutritious beans rich in proteins. Just how these plants draw water approaching their roots in soil has now for the first time been observed in three dimensions by a University of Potsdam team at the HZB-BER II neutron source in Berlin. To accomplish this, they worked with the HZB imaging group to improve the temporal resolution of neutron tomography more than onehundred-fold so that a detailed 3D image was generated every ten seconds. This ultrafast neutron tomography is generally suitable as well for analyses of dynamic processes in porous materials. [...].

    Writing with the electron beam: now in silver

    For the first time an international team realized direct writing of  silver nanostructures using an electron beam applied to a substrate. Silver nanostructures have the potential to concentrate visible light at the nanoscale. Potential applications include sensor design to detect extremely small traces of specific molecules, as well as devices for optical information processing. [...].
