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...
216 when the Section 8) and full-width-half- maximum (FWHM) of the wavelength is 3 nm and the FWHM of the incident laser divergence angle is 4° (± 2°), which provides sufficiently large enhancement of the out-of-plane component of the near field energy for dark exciton brightening....

The energy level diagram for trivalent rare earth is commonly referred to as Dieke diagram (Peijzel et al., 2005). This diagram is useful because the energies of the J multiplets vary by only a small amount in different host crystals. The diagram allows rapid identification of the energy ...
