Previous studies obtained microcrystals extracted from bulk single crystals with the out-of-plane crystallographic axis [símbolo] perpendicular to the applied magnetic field [símbolo] and parallel to the current flow. The new method orients [símbolo] parallel to [símbolo] and perpendicular to the current. Magnetotransport measurements at 2 K on Bi2Se3 samples fabricated using both methods reveal differences in zero-field resistivity and charge carrier mobility, demonstrating the impact of the crystal orientation in which the microcrystal is extracted on the electrical transport properties.2025http://zaguan.unizar.es/record/16084810.1557/s43579-025-00719-8http://zaguan.unizar.es/record/160848oai:zaguan.unizar.es:160848info:eu-repo/grantAgreement/ES/AEI/PID2023-146451OB-I00info:eu-repo/grantAgreement/ES/MCIU/PID2020-112914RB-I00info:eu-repo/grantAgreement/ES/MICINN/CEX2021-001144-S-20–9info:eu-repo/grantAgreement/ES/MICINN PRE2022-103314MRS Communications (2025), [8 pp.]byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
