Organic, polymer, and oxide-based transistors are among the alternatives to silicon being considered for flexible display pixel circuitry. Carrier mobilities in the semiconductors now exceed those of amorphous silicon, and switching voltages can be below 2 V. In this presentation, we focus on gate dielectrics compatible with these semiconductors. First, we consider polymer dielectrics in which static...
We report the observation of an optical topological transition in the iso-frequency surface of a non-magnetic anisotropic metamaterial. Enhancement in the photon density of states is demonstrated as a result of this transition.
