Resumen: We propose a new in situ microfabrication method using focused electron/ion beam processing to study the influence of crystal orientation on magnetotransport properties. 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.
