Abstract
Optical-absorption and luminescence measurements on and diamonds establish that the indirect energy gap is 13.6±0.2 meV higher for than for diamond. Zero-parameter calculations, allowing for the changes in electron-phonon coupling and lattice parameter, give an estimated shift of 16.5±2.5 meV.
