• ][13]. When this type of material is considered for an application in organic transistors, specific requirements for the gate insulator have to be fulfilled. The most important of these requirements comprise high capacitance, substantial dielectric strength, high purity and processability of the

• properties of Parylene C, treated here as independent application fields, are found useful in a fabrication of high performance organic transistors. First of all, major advantages of the chemical structure and the deposition procedure of this polymer are pointed out with the focus on its application as a

For example, they have been explained based on the energetic crossover (and thus the increase of the spin mixture) of spin sublevels of correlated polaron

Our results show for the first time ultrasmall magnetic-field effects in organic transistors. Under moderate drain voltage conditions; there is a positive
