COMPOSITE CHALCOGENIDE MATERIALS AND DEVICES

An electrical device includes a composite switching material. The composite switching material includes an electrically switchable component and a non-switchable component. In one embodiment, the composite switching material includes a heterogeneous mixture of at least one chalcogenide material and at least one dielectric material. The composite switching material is disposed between two electrodes and the switchable component is transformable from a resistive state to a conductive state upon application of a voltage between the two electrodes, without changing phase.
