Does Topology Enhance Thermoelectric Efficiency? A Case Study in Bismuthene

Two-dimensional (2D) bismuth (Bi) layer, known as bismuthene, exhibits \(Z2\) topological bulk states due to large spin-orbit coupling that inverts the bands. Using the tight-binding method, we calculate the band structure of buckled bismuthene to understand its topological and trivial phases. We de...
