Atomically precise step grids for the engineering of helical states
Conventional spin-degenerate surface electrons have been effectively manipulated by means of self-organized nano-arrays. Of particular interest are one-dimensional, step superlattices at vicinal surfaces, because their fundamental behavior can be understood through simple model theory, and they can be utilized to imprint strong surface anisotropies in electron transport devices. In this …
