GaAs grown by liquid phase epitaxy (LPE) and free from deep levels is well suited for studying vanadium-related levels in bulk GaAs. LPE growth of GaAs:V was carried out and it is found from deep-level transient spectroscopy (DLTS) that vanadium gives rise to an electron trap at 0.19±0.01 eV below the conduction band edge with a capture cross section of $4X10^{-16} cm^2$. This could be a level different from the electron trap at 0.14 eV reported for LEC-grown GaAs:V due to the formation of different complexes under different growth conditions.
