Abstract:
Kim et al. have reported a dependence of the infrared
excitation energies of boron acceptors in diamond on the
isotopic mass of the carbon atoms. We show that this change can
be quantitatively interpreted as induced by a change in the
hole effective mass. (C) 2001 Elsevier Science Ltd. All rights
