Abstract
We present first principle investigations on in-plane phase engineered nanoribbons with two different widths. 2H and 1T' phases of WSe2 are joined along x-direction, which forms an armchair type interface. The low values of formation energy shows that these structure are energetically stable. The study of electronic structure reveals that they are metallic and the electronic conductivity varies significantly with ribbon length. The ribbons show anisotropic dielectric response compared to constituent monolayers. Optical properties alter considerably for these hetero-systems showing potential for tunable opto-electronic applications. © 2019 Author(s).
