Does Topology Enhance Thermoelectric Efficiency? A Case Study in Bismuthene

Muhammad Gaffar, Sasfan Arman Wella, Eddwi Hesky Hasdeo

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…
