Zusammenfassung: | The transport properties of [2,2]-paracyclophane thin films prepared by molecular beam epitaxy were studied by space-charge-limited current measurements. This organic semiconductor, which has a three-dimensional π-system comparable to that of C60, is an interesting material for molecular electronic applications due to its remarkably high mobility and its insensitivity against photo-oxidation. The current–voltage characteristics were recorded using a coplanar electrode geometry which 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 cm2 V−1 s−1 were observed at room temperature. |
