In the latter case breaking of bonds at a surface leads to mid-gap states. One can say that vanishing hopping integrals at the surface is the main reason for this effect. On the other hand, in silica, changing Si–O hopping integrals does not result in states with energies less than ...

It is shown that these state differ ...
Thus, there is a forbidden region for eigenstates of electrons in pure materials that is known as the energy gap. This energy gap increases with the increase in energy; i.e., the higher the energy of the band, the larger its width in energy. This significant fact, which is essentially ...
In this experiment, the Friedrich-Wintgen BIC serves as a stable resonator with a high Q-factor and provides an efficient radiation channel for XDdirectional emission30,37. We designed a suspended Si3N4PhC slab (thickness is 233 nm) with a square array of cylindrical holes (periodicity is ...

This anti-bonding coupling leads to the upward shift in VBM at the Γ-valley, resulting in the transformation from a direct gap to an indirect gap. The difference in VB energy of hBN and MoS2 at the Γ-point is ~400 meV, which is much smaller than that in CB, and this relatively...

The solutions obtained (of the linear as well as the nonlinear equations) are interesting since several arguments suggest that the Cauchy problems for these equations are ill-posed, and therefore the specification of the initial conditions is a delicate issue. It is also shown that some of these...
