Organic crystals: From semi- to superconductors — •Antonia Morherr, Sebastian Witt, Christian Klein, Jan-Peter Bäcker, and Cornelius Krellner — Physikalisches Institut, Goethe-Universität Frankfurt am Main, Deutschland
Intercalated aromatics became attractive in the last years as new class of organic superconductors [1]. Potassium-intercalated picene and phenanthrene showed superconducting transition temperatures of 18 and 5 K. Intercalated Dibenzopentacene reached a TC of 33.1 K [2], Coronene TCs are between 3.5 K and 15 K [3]. So far, all experimental results are obtained on polycrystals, therefore the growth and investigation of single crystals of these materials are of importance for further research in superconductivity. We apply horizontal vapor growth and solution growth intercalation techniques for deeper understanding of the physical properties. Doping with potassium is achieved by co-crystallization and two zone gas transport. In this contribution, we present the physical and structural properties of intercalated single crystals and powder samples. To this end magnetization, resistivity and heat capacity was measured down to 1.8 K.
