Energy band structure, total and local partial densities of states, spatial distribution of electronic density of 2H-SnSe₂ have been calculated using the densitym functional theory method in LDA and LDA+U approximations ...

The electron behavior in incommensurate phase in Sn₂P₂Se₆ has been considered as the motion in the Mathieu potential. A simple model of effective potential change under a transition incommensurate – domain-like structure ...
