The organic superconductivity is a very interesting phenomenon. Electronic conduction proceeds in organic molecular conductors through the transport of free charges (electrons or holes) between π-like molecular orbitals of neighbouring open shell molecules. Organic nanoscale science and technology relies on the control of phenomena occurring at the atomic level. Here we use real-time in-situ extremely sensitive capacitive measurements in order to analyze and control the molecular growth process. In combination with ex-situ ellipsometry we obtain electronic properties of the SAM layers that are different to that of the molecules in the liquid state. For instance permittivities εSAM > 50 are measured for SAMS made from APTES or related test molecules which is comparable to high-k material. The superior properties of the SAM might be an indication of the quality (density, order, and orientation) for the SAMs. The resulting molecular layers have a high potential for a number of electronic applications including cryogenic applications. |
