Abstract
An electronic device includes a substrate supporting mobile charge carriers, insulative features formed on the substrate surface to define first and second substrate areas on either side of the insulative features, the first and second substrate areas being connected by an elongate channel defined by the insulative features, the channel providing a charge carrier flow path in the substrate from the first area to the second area, the conductivity between the first and second substrate areas being dependent upon the potential difference between the areas. The mobile charge carriers can be within at least two modes in each of the three dimensions within the substrate. The substrate can be an organic material. The mobile charge carriers can have a mobility within the range 0.01 cm2/Vs to 100 cm2/Vs, and the electronic device may be an RF device. Methods for forming such devices are also described.
