Chemical bonding and optical bowing in III-nitrides solid solutions
Chemical bonding and electronic properties of III-nitrides solid solutions are studied using a model empirical pseudopotential method in modified virtual crystal approximation taking into account positional and compositional disorder. The changes in chemical bonding are analyzed in different ionicit...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Chemical bonding and electronic properties of III-nitrides solid solutions are studied using a model empirical pseudopotential method in modified virtual crystal approximation taking into account positional and compositional disorder. The changes in chemical bonding are analyzed in different ionicity models. The bowing is mainly caused by compositional disorder, volume deformation effects and valence charge redistribution in the alloys. The connection between the value of the bowing and basic parameters of the materials is found. |
