Department of Chemistry

The Department of Chemistry at the Technische Universität München has taken great efforts to meet the requirements of a rapidly changing scientific environment.
We offer a broad diversity of subjects: The traditional areas of Inorganic Chemistry, Organic Chemistry, and Physical Chemistry have been enriched by Chemical Technology, Radiochemistry, Food Chemistry, Theoretical Chemistry, and Hydrochemistry many years ago. The last years saw new expansions into the fields of Biochemistry and Construction Chemistry. [More...]

Layered semiconducting black arsenic phosphorus as an alternative to silicon

Graphene gets competition

Graphene, the only one atom thick carbon network, achieved overnight fame with the 2010 Nobel Prize. But now comes competition: Such layers can also be formed by black phosphorous. Chemists at the Technische Universität München (TUM) have now developed a semiconducting material in which individual phosphorus atoms are replaced by arsenic. In a collaborative international effort, American colleagues have built the first field-effect transistors from the new material. [more ...]
