The growth of heavily carbon doped p-InGaAs (∼6.5x1019cm-3) lattice-matched to InP is reported. Growth is achieved by low pressure metalorganic chemical vapor deposition (LP-MOCVD) using all methyl metalorganic sources and liquid CCl4. The impact of growth temperature and CCl4 flow rates on growth rate reduction and alloy compositional change was investigated. Post-growth isothermal and isochronal annealing experiments were performed on the carbon doped InGaAs layers and a quantitative analysis of carrier activation is presented using Hall and secondary ion mass spectroscopy measurements. Reduced self-compensation by carbon displacement from indium to arsenic site, as well as, reduced hydrogen passivation are suggested as possible mechanisms responsible for carrier activation upon thermal annealing.
