|ψk,n(r)|2 where the sum runs over the occupied bands n and wave vectors k of the supercell BZ and ψk,n(r) is the electronic wave function. Figure 2.2(a) shows the contour plots of the electronic valence charge density of the GaAs/AlAs (001) interface simulated by a 3 + 3 ...
We show that a one-dimensional metal-dielectric (MD) periodic structure can possess an omnidirectional band for a p-polarized wave, owing to the compensation effect of power flow in the parallel direction in the metal. When the net power flow in the direction parallel to the MD interface is...

In the sense, a reduction of the gap could be regarded as intrinsic in correlated d bands under the optical pumping. In Fig. 2d, on the other hand, V of CuO in fact shows no noticeable shift even though C moves similarly to NiO. Moreover, the two-dimensional plots of spectra of TR...
The solid state structure of titanium is: hcp (hexagonal close-packed). More crystallographic data... Titanium: biological data Human abundance by weight: (no data) ppb by weight Titanium has no biological role. The metal is regarded as hypoallergenic. ...
and intermediates transformation17,18. As such, sufficient electron in metal sites is essential to stabilize the intermediates and enable bond breaking and recombination, that is, the metal sites are required to have strong electron localization capability to store electrons for the activation of interf...
Historically, the fundamental test bed of correlated solid electrons has been the 3d transition metal oxide, which includes NiO that has then been long considered to be MHI. In MHI, a band gap opened between the upper Hubbard band (UHB) and the lower Hubbard band (LHB) is scaled by the ...
A thin layer of metal is deposited on the surface of the sample by vacuum evaporation. The purpose is to improve the resolution of the SEM and to increase the signal strength so that the SEM can show the detailed features of the sample surface more clearly. The SEM morphology analysis of ...
FTIR spectroscopy was implemented to characterize the frame structure of the materials and shown in Fig. 4. The strong bands at around 3427 cm−1 is attributed to the stretching and deformational vibrations of the residual water71. The asymmetrical stretching of Si–O–Si at about...
(siloxane) vibrations, respectively. Moreover, the signals appeared at 1633 and 1,470 cm−1are attributed to the stretching vibrations of the isocyanurate ring. Also, the absorption bands at 1,284–1,177 and 1,134–1,045 as well as 630–572 cm−1were assigned to the O = S...
