Neopentyl iodide (NpI) has been shown to be an inefficient carbon-doping source for GaAs and AlGaAs, but is some two orders of magnitude more efficient in AlAs. This difference in NpI doping behaviour is attributed to a significant difference in the surface chemistry of NpI on AlAs, possibly due to a lack of reactive hydrogen during layer growth.
