Electronic-Field Control of Two-Dimensional Electrons in Polymer-Gated-Oxide Semiconductor Heterostructures

A defect-free and electronically abrupt polymer/oxide interface can be achieved by spin-coating of PEDOT:PSS on ZnO-based heterostructures. The interface yielding Schottky contact leads to the successful modulation of quantum 2D transport in MgZnO/ZnO interfaces via the electric-field effect, which indicates that the polymer/oxide interface enables a high-mobility field-effect transistor.
