Abstract
Various methods and devices for touch screens using topological insulators are provided. One of the touch screen devices includes a touch sensor layer including a three-dimensional '3D' topological insulator that maintains an electric charge over opposing outer surfaces of the 3D topological insulator. The touch screen device also includes electrodes electrically connecting the opposing outer surfaces of the 3D topological insulator. The touch screen device also includes a controller that determines a position at which an object touches the touch screen device based on a change in the electric charge over the opposing outer surfaces.
