Xm. Fang et al., METALORGANIC CHEMICAL-VAPOR-DEPOSITION GROWTH OF GAAS-ER USING ER(C4H9C5H4)(3), Journal of electronic materials, 23(12), 1994, pp. 1269-1272
Erbium doped GaAs has been grown by metalorganic chemical vapor deposi
tion using a novel liquid precursor: Tris(n-butylcyclopentadienyl)erbi
um, Er(C4H9C5H4)(3). Erbium doping as high as 1.2 x 10(19)cm(-3) has b
een realized. The morphology was excellent at growth temperatures near
620 degrees C. The erbium concentration was found to depend on growth
temperatures due to incomplete pyrolysis of the erbium metalorganic c
ompound. The erbium-related PL intensity was decreased when the erbium
concentration exceeded similar to 1.2 x 10(19)cm(-3).
