The prize, worth €1500, was donated by Micropelt, thermoelectric specialist from Freiburg, and DTG. The DTG Young Investigator Award has been presented for the first time.
This first presentation of the DTG Young Investigator Prize was made during the annual meeting of the German Thermoelectric Society (DTG) on 19th November 2009 in Freiburg. Solid-state physicist from Tübingen, Dr. Nicola Peranio, was awarded the prize for his doctoral research work on the structure, composition and properties of bismuth telluride. The prize was presented at the Fraunhofer Institute for Physical Measurement Techniques IPM.
Doctoral work on bismuth telluride awarded
Dr. Nicola Peranio's award-winning work showed that the low thermal conductivity of bismuth telluride, which is responsible for its excellent thermoelectric properties, is caused by a special structural characteristic of the material. Thus, the heat expansion in the crystal lattice in bismuth telluride is impeded by a periodic nanoscale structure. Dr. Nicola Peranio not only succeeded in imaging the structural change using transmission-electron microscopy but also provided a theoretical description.
Technology of the future: thermoelectrics
Thermoelectrics is used to convert heat into electricity or electricity into heat. Thermo¬electric energy converters, in the form of heat pumps, can use an electric current to produce a temperature difference, or use a temperature difference to generate an electric current. Both have huge economic and environmental potential. For example, the conversion of unused excess waste heat into electrical energy can potentially build an enormous new energy market.
DTG promotes young research scientists
The Young Investigator Award is donated jointly by the DTG and Micropelt from Freiburg. The prize is awarded for the best qualification work of the year in thermoelectrics which has taken place in Germany. The essential criteria for evaluating the work produced during doctorates, diplomas, and master's degrees are scientific or technological originality and a potential for new solutions or applications. This year, the prize has been awarded for the first time. The prize - worth €1500 - was donated by thermoelectrics specialist Micropelt and the German Thermoelectric Society.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Hitzewellen in der Arktis, längere Vegetationsperioden in Europa, schwere Überschwemmungen in Westafrika – mit Hilfe des deutsch-französischen Satelliten MERLIN wollen Wissenschaftler ab 2021 die Emissionen des Treibhausgases Methan auf der Erde erforschen. Möglich macht das ein neues robustes Lasersystem des Fraunhofer-Instituts für Lasertechnologie ILT in Aachen, das eine bisher unerreichte Messgenauigkeit erzielt.
Methan entsteht unter anderem bei Fäulnisprozessen. Es ist 25-mal wirksamer als das klimaschädliche Kohlendioxid, kommt in der Erdatmosphäre aber lange nicht...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
