SdH oscillations in Cd₃As₂ nanoplate with low-Fermi-level. a, b The extracted SdH oscillations of sample #2 at different angles a and LL spectrum b. c Landau fan diagram in the low field regime. d The angle dependence of normalized oscillation frequency ratio. F _s denotes the 2D oscillation frequency and F _s0 represents the 2D oscillation frequency at θ = 0°. The inset is a sketch of the magnetotransport geometry. e Comparison of \(\Delta R\) and \( - \frac{{{{\rm{d}}^2}R}}{{{\rm{d}}{B^2}}}\) curve. Two extra hidden peaks are revealed by \( - \frac{{{{\rm{d}}^2}R}}{{{\rm{d}}{B^2}}}\) while being less obvious in the \(\Delta R\) curve
