Bowing Parameter

The optical gap bowing parameter of ternary Ni1−xZnxO solid solutions is determined to be b = −0.93 ± 0.05 eV, where the negative value of the bowing indicates a repulsive interaction between the ligand O-2p and metal Ni-3d orbitals.

Experimental Values

Room temperature electroreflectance measurements have been made on samples of AlxGa1−xAs alloys, grown by liquid epitaxy. The variation of the different band transition energies, E0, E1, E2, etc. has been determined as a function of composition x. For each transition energy, the data have been fitted to the relation E = a + bx + cx2 and hence the bowing parameter c determined. These experimental values of c are compared with the predicted values of Van Vechten.
