Abstract
The transitions in Te donors in GaP have been observed. Together with similar data for Si and S donors, Faulkner's effective-mass (EM) calculations yield an ionization energy of 89.8±0.3 meV for Te donors. Conduction-band effective masses consistent with all the data for these GaP donors are and . The effects of uniaxial stress on the "two-electron" transitions in the recombination of excitons bound to neutral Te donors in GaP are consistent with the final donor states observed being -like with a valley-orbit splitting.
