Research News: Superconducting organic thin films have been produced for the first time making use only of dry processes. The vacuum‐evaporation method is suitable for the production of thin films of BEDT‐TTF iodide either from electrochemically produced BEDT‐TTF iodide or directly from BEDT‐TTF and iodine. The insulating films formed in the deposition process are converted to the conducting form by annealing and analyzed using X‐ray diffraction (see Figure). The ‘dry’ nature of the process is advantageous as solvents can damage the fine crystals formed and make the production of homogeneous thin films difficult.
