Fig. 5: Estimation of carrier density and mobility in each t2g band.
From: Stoichiometric control of electron mobility and 2D superconductivity at LaAlO3-SrTiO3 interfaces
a The evolution of total carrier density nT (solid circle) and carrier density for electrons occupied in lower energy dxy band, nd(xy), (open square) and upper dxz/yz band, nd(xz/yz) (solid triangle), as a function of VG, extracted from two-band model fit. b The extracted values of corresponding electron mobility μd(xy) and μd(xz/yz) as a function of VG. The shaded area represents two-band region in the phase diagram. c, d The estimated value of mean free path for dxy electrons \({l}_{mfp}^{{d}_{xy}}\) and dxz/yz electrons \({l}_{mfp}^{{d}_{xz/yz}}\) respectively. The shaded gray area is the estimated value of coherence length adapted from ref. 15.
