Low-energy theory for electron-phonon scattering in topological insulators
Final Report Abstract
In this project, we have developed and applied a transport theory for topological insulators and the related Weyl semimetal materials which takes into account electron-phonon interaction effects. Our analytical theories show in detail how topologically nontrivial surface states will affect the electrical resistivity tensor for different device types (e.g., slab or nanowire geometry). By and large, the work has proceeded as anticipated, and we have even enlarged the scope by including Weyl semimetal materials. We expect that these results will guide future experiments and thereby contribute to elucidating the remarkable effects of topological principles in condensed matter systems. In addition, they are likely to motivate additional theoretical work along these lines.
