A low-pressure metalorganic chemical vapor deposition of CuAlSe2 epitaxial films was performed using several kinds of metalorganic precursors. The film quality varied remarkably depending on the source precursors. Free exciton emission at 2.739 eV was observed in the CuAlSe2 films grown using triisobutylaluminium and diethylselenium, both ofwhich have lower decomposition temperatures.
