Nano-crystals created in wet chemicals, meaning in a solution, can already be found in the latest TV screens or in image-making diagnostic procedures in medicine. A research group headed by CUI member PD Dr. Christian Klinke from the Institute of Physical Chemistry at Universität Hamburg has now demonstrated a special feature in such nanostructure: in lead sulfide nano platelets, circular-polarized lights (used for example in 3D movies) can direct electrons and create oriented currents. This makes cheaper and better-performing transistors and computer chips conceivable. The research findings have now been published in the journal Nature Communications.
