Wet-chemically produced nanocrystals are becoming more and more powerful. They are already used in the background lighting of the latest generation of flat panel displays. In the future they will be used increasingly as active elements, which produce higher color brilliance. They are also used in other fields of application, e.g., for medical diagnosis and treatment. Now a research group around Dr. Christian Klinke from the University of Hamburg has succeeded in substantiating electronic spin effects in such nanoplatelets. In this way, more cost-effective and more powerful transistors and computer chips with lower power consumption are conceivable in the future. The two-dimensional materials are also advantageous since they can be produced inexpensively and on a large scale in a chemical laboratory and are nevertheless of the highest quality, as shown now.
