M. Mcelhinney et al., QUANTUM TRANSPORT MEASUREMENTS ON SI DELTA-DOPED AND SLAB-DOPED IN0.53GA0.47AS GROWN BY MOLECULAR-BEAM EPITAXY, Journal of crystal growth, 150(1-4), 1995, pp. 266-270
A series of high quality delta-doped In-0.53,Ga0.47As samples have bee
n grown lattice matched to InP with design doping densities in the ran
ge 2 x 10(12) to 5 x 10(12) cm(-2). Analysis of the individual sub-ban
d densities deduced from the Shubnikov-De Haas effect shows that both
spreading and amphoteric behaviour increase with doping density.
