The molecular beam epitaxial growth of Si delta -doped donor planes within InGaAs layers is described. The results of Hall and C-V characterization measurements of single and double delta -doped InGaAs channel layers are presented. It is shown that high sheet carrier concentrations approaching 3.8*1013 cm-2 can be achieved. Improved carrier transport in double delta -doped channels for FET applications is proposed and experimentally confirmed by decreased sheet resistance values obtained from double delta -doped structures.
