Figure 3: 2D quantum oscillations of the conduction at γ-Al2O3/STO interfaces.

Figure 3

(a) Longitudinal resistance, Rxx, as a function of magnetic field with visible SdH oscillations (arrowheads) under different tilt angle, θ, at 0.3 K for the d=2.5 uc sample. (b,c) Amplitude of the SdH oscillations, ΔRxx, under different θ versus the reciprocal total magnetic field and the reciprocal perpendicular magnetic field component, respectively. The SdH oscillations depend mainly on the reciprocal perpendicular magnetic field component, particularly in the θ angle of 0°–33°, which suggests a 2D conduction nature of the γ-Al2O3/STO interface.
