Nonsaturating Linear Magnetoresistance Manifesting Two-Dimensional Transport in Wet-Chemical Patternable Bi₂O₂Te Thin Films

Unusual Janus Bi2TeSe2 Topological Insulators Displaying Second-Harmonic Generation, Linear-in-Temperature Resistivity, and Weak Antilocalization

“…It is interesting to note that when the applied magnetic field is normalized to B cos θ, all of the curves overlay with each other, showing that only the magnetic-field perpendicular component B cos θ contributes to the transport process of the nanosheets. Such a property is a signature of the existence of a 2D transport channel in the sample. − For 2D-dominated transport, only the perpendicular magnetic field ( B // c axis) could affect the magnetotransport behavior, while the horizontal magnetic field plays no role. When the magnetic field deviates from the perpendicular configuration, the magnetotransport signal will only respond to the perpendicular component of magnetic fields, where B cos θ is the effective applied magnetic field.…”
