Topological matter is without a doubt the topic of the decade. Not only do topological insulators offer scientists a huge playground of fundamental phenomena to study, they are also extremely promising candidates as future materials for computer processing devices and memory applications. This wide array of possibilities can only be achieved if the material properties can be optimized to yield the theoretically predicted behavior (insulating bulk + metallic spin polarized surface). I will thus briefly discuss our realization of high quality topological materials in thin films of SnTe – a topological crystalline insulator. I will end by discussing a device proposal, based on the general properties of a topological insulator.
