The Curie temperatures up to 150 K were reported in low-temperature annealed [Ga,Mn]As epilayers. The higher Curie temperatures were found to result from an enhanced free hole density. It was found that in addition to the carrier concentration, the sample thickness limited the maximum attainable Curie temperature in the material.
