The missing ion adds charge to the surface bands leading to strong charge transfer and to new physics. We find that the surface layer is an orbital-selective Mott insulator, with the \(d_{3z^2 - r^2}\) orbitals in a Mott insulating state (see the large self-energy shown in Fig. ...
They're one of those bands for me where I've made it a point to have every song, and I like them all. Literally anything Claypool is right up my alley. My favs are probably Lacquer Head, Golden Boy, Puddin' Taine, Mr. Knowitall, Pudding Time, DMV, My Name is Mud, Sgt. Baker,...
Moiré superlattices of twisted bilayer TMDs have been recently shown to host shear solitons, topological point defects and ultraflatbands close to the valence band edge. Performing structural relaxations at the DFT level is a major bottleneck in the study of these systems. We show that the ...
Changes of the electronic structure at the MIT are discussed in relation to the structural transformations occurring simultaneously. The analysis is based on a unified point of view of the crystal structures of V6O11, VO2, and V2O3. This allows to group the electronic bands into states beha...
The FT-IR spectrum of the purified Fe(salen) shows typical IR bands of Fe(salen) at 1619, 1384, 1336 and 1302 cm − 1, while no vibration bands of Fe–O at approximately 580 cm − 1 (related to magnetite) were seen. In addition, a band due to asymmetric Fe–O–Fe stretching...
Band dispersion for the SIO supercell on STO (a–c). Different colors correspond to projections of bands on the different IrO2planes in the structure (blue, red, and green correspond respectively to the first, second, and third closest IrO2plane to the STO interface). Calculations are under...
Over the past several decades, metal Additive Manufacturing (AM) has transitioned from a rapid prototyping method to a viable manufacturing tool. AM techno
In order to explain the observations, we propose that there is a distribution of shallow surface states, and the carriers in the bands can easily transfer into and thermally out of these states (Figure 4A). We depict these as shallow electron states just below the conduction band, but these...
The difference is that in both perovskite structures (Pmn21 and Pmm2), because nominally Bi3+, Pb2+ and O2−, due to charge neutrality Ti must have a formal valence of Ti3.5+, i.e., every Ti atom has 0.5 electron in the 3d conduction bands (no charge disproportionation is found ...
