Growth Studies on Organic Charge Transfer Materials: (ET)2Cu(NCS)2 — •Kerstin Keller, Florian Roth, Yoon-Jeong Lee, and Michael Huth — University Frankfurt, Max-von-Laue-Str. 1, 60438 Frankfurt am Main
The growth of organic thin films of Pentacene and BEDT-TTF (ET) prepared by organic molecular beam deposition (OMBD) is studied and the evaporation process is modeled by Monte Carlo simulations. By coevaporation of ET and Cu(NCS)2 the formation of the charge transfer salt (ET)2Cu(NCS)2 is investigated, where the superconducting kappa-phase is of special interest. The thin films are characterized by x-ray diffraction. With in-situ shadow mask technique different functional device structures such as field effect transistors (FET) and tunneling contacts can be prepared. This enables us to investigate the electronic properties with low temperature measurements.
