"description": "Materials that can host Majorana zero modes gained a lot of attention in recent years due to the possibility to engineer topologically protected quantum computing platforms. Promising candidates are heterostructures of topological insulators and superconductors. Here we present density-functional-theory-based calculations for Pd-doped Bi\u2082Te\u2083 and Pd(Bi,Te)<sub>x</sub> (x=1,2) in order to shed light on the superconducting properties in the self-formed superconducting phase when Pd is deposited on top of the topological insulator Bi\u2082Te\u2083.\nThis dataset accompanies a joint experiment/theory publication and publishes the related density functional theory calculations for:\n- relaxed geometries for Pd intercalation in the Bi\u2082Te\u2083 vdW gap\n- electronic structure of PdTe and PdTe\u2082 compared to alloy phases of Pd(Bi,Te) and Pd(Bi,Te)\u2082, collectively referred to as \"xPBT\"\n- calculations for the superconducting state of xPBT phases within the Kohn-Sham Bogoliubov-de Gennes method",
