Transport properties of [2,2]-paracyclophane thin films — •Bruno Gompf1, Wenping Hu1, Martin Dressel1, Jens Pflaum2, and Dieter Schweitzer2 — 11. Physikalisches Institut, Universität Stuttgart — 23. Physikalisches Institut, Universität Stuttgart
The transport properties of [2,2]-paracyclophane thin films prepared by molecular beam epitaxy were studied by space charged limited current measurements. This organic semiconductor, which has a three dimensional π-system comparable to that of C60 is an interesting new material for molecular electronics applications due to its remarkably high mobility and its insensitivity against photo-oxidation. The I-V characteristics were recorded using a coplanar electrode geometry. This geometry has the advantage, that after deposition no further processing of the organic semiconducting layer is necessary. In polycrystalline films hole mobilities up to 10−2 cm2V−1s−1 were observed at room temperature.
