Figure 1From: Magnetotransport study on as-grown and annealed n- and p-type modulation-doped GaInNAs/GaAs strained quantum well structuresSdH oscillations. (a) Raw experimental magnetoresistance data and (b) second derivative of the SdH oscillations at different temperatures for the as-grown N-free (y = 0) and N-containing (y = 0.009) samples.Back to article page
