Room-temperature Bose-Einstein condensation? Hideyo OKUSHI, AIST Tsukuba Diamond Research Center, Japan The AIST Tsukuba Diamond Research Center has
observed extremely sharp 235-nm exciton emission in fabricated single-crystal diamond film semiconductors at 300K. If the exciton lifetimes are long enough it is possible that Bose-Einstein condensation can occur in these diamond films, even at room temperature.
