| Abstract | Bismuth telluride, in Bi2Te3 phase, is an archetype of three-dimensional topological insulator. This material presents topological surface states (TSS), shaped like a Dirac cone, crossing the material band gap [1]. These TSS present linear dispersion, resulting in massless Dirac fermions in the surface with extremely high Fermi velocities and bulk insulator behavior. The massless Dirac fermions possess spin-locked to the momentum and are protected from backscattering due to time reversal symmetry, which open-up several possibilities of applications in spintronics and quantum computing [2]. However, presence of structural defects in this compound changes the chemical potential, resulting in bulk conduction which overwhelms the metallic surface states, hampering these topological states from electrical measurements. By controlling the chemical potential of the sample is possible to tune from p to n, passing through a bulk insulator phase. A truly topological insulator compound must have the Fermi level located inside the material band gap, i.e., crossing only the TSS [3]. In this work, we applied a Monte Carlo epitaxial growth model to study the case of bismuth telluride. By changing the growth conditions in the model, we monitored the formation of structural defects. The computational model was validated to a set of experimental data. The simulation results were able to explain a p-to-n transition that occurs by increasing the substrate temperature in which the epitaxial films are grown. References: [1] Y.L.
