Abstract

Behavior of carbon (C) doping in a (1^-101)AlGaN has been investigated by grazing incidence FTIR analyses at room temperature. The sample was grown by MOVPE on (1^-101)facets of GaN triangular stripes made on (111)Si substrate. Intentional C doping was performed by introducing C₂H₂ into the reactor during the growth. In the FTIR spectra, a C related LVM mode was found out at 950 cm^-1 which was associated with A₁(LO) mode of AlN at 890cm-1. The behavior was similar to the results found in an un-intentionally Al doped GaN sample. Linear chain model with an effective mass gives the LVM energy of Al-C bond at 930 cm^-1, a little lower than the experimental observation. The C doping on the N site might be performed forming a complex with additional elements.
