Infrared and Raman spectroscopy of acceptor-bound holes : boron acceptors in isotopically controlled 'blue' diamonds.
The extremely rare, nitrogen-free, boron-doped diamonds display a Lyman spectrum in the infrared associated with a substitutional group III acceptor. The Lyman spectrum reveals a unique example of 'self-energy' corrections to the effective mass theory for the same substitutional acceptor but located in a host differing merely in its isotopic composition. The Lyman spectrum, observed as a function of temperature, shows the existence of a close pair of 1s ground states separated by {approx}2 meV. The electronic Raman spectrum discloses a line at 2.07(1) meV in natural and 2.01(1) meV in {sup 13}C diamonds corresponding to the transition between the spin-orbit split 1s(p{sub 3/2}) and 1s(p{sub 1/2}) ground states. Polarization features show the transition to be dominantly {Gamma}{sub 5} in character, placing an upper limit on the ratio of the non-spherical Luttinger parameters of the valence band; Zeeman and piezospectroscopic effects fully support the assignment.
