Discussion— In conclusion, two canadian researhcers have proposed a minimal two-band model which reproduces the main features of the Cu dzx and dzy flat bands predicted to appear in a ...

In our previous work, the concept of critical region in a generalized Aubry–André model (Ganeshan–Pixley–Das Sarma’s model) has been established. In this work, we find that the critical region can be ...

The band structure of the dilute-As GaNAs material is explained by the hybridization of localized As-impurity states with the valance band structure of GaN. Our approach employs the use of Density ...
