Abstract
Metal-organic (MO)CVD processes using two different precursors, (La(tmhd)3 and La(tmod)3), have been investigated. In-situ Fourier transform infrared (FTIR) spectroscopy investigations and thermal analysis have provided information on their thermal robustness during the sublimation processes and mass-transport properties during MOCVD experiments. Both precursors can be efficiently vaporized in the temperature range 160–230 °C even though La(tmod)3 exhibits higher volatility. Lanthanum oxides have been efficiently deposited using a direct liquid injection (DLI) equipped MOCVD reactor in the temperature range 350–500 °C for both precursors. The effect of the addition of tetraglyme to the precursor solution has been evaluated. Films mainly consist of different phases of La2O3 and LaO(OH), while the carbon-containing La2O2CO3 phase was observed only on the surface, with no relevant carbon contamination being present in the bulk of the film.
