In this work we use angle resolved photoemission to determine the electronic structure of a 2DEG stabilized in the (111)-oriented surface of the strong spin orbit coupling material KTaO3. Our measurements reveal multiple sub-bands that emerge as a consequence of quantum confinement and form a ...
resolved photoemission spectroscopy. The Fermi surface and band structures of La3Ni2O7are observed and compared with the band structure calculations. Strong electron correlations are revealed which are orbital- and momentum-dependent. A flat band is formed from the Ni-3d{}_{{z}^{2}}orbitals ...
The strong screening of π state imposes the formidable chal- lenge in forming spectroscopically resolved series π exciton states. Motivated by the desirably stable σ exciton in graphene stacks, we estimate 2s-2p splitting of σ excitons in a suspended graphene to be in the order ...
After giving a concise overview of the current knowledge in the field of quantum mechanical bonding indicators for molecules and solids, we show how to obtain energy-resolved visualization of chemical bonding in solids by means of density-functional electronic structure calculations. On the basis of ...
We report an angle-resolved photoemission spectroscopy (ARPES) study on IrTe2 which exhibits an interesting lattice distortion below 270 K and becomes triangular lattice superconductors by suppressing the distortion via chemical substitution or intercalation. ARPES results at 300 K show multi-band Fermi ...
Time-resolved emission data acquired in room-temperature CH2Cl2nsolutions revealed excited-state lifetimes of 14.9 0.7, 8.1 0.4, 8.2 0.4, 5.6 0.3, and 5.0 0.3 nsnfor complexes 1 5, respectively. The emission in each case is assigned to decay of the ReIn-based 3MLCTnexcited state; the ...
Next, we analyze the properties of the band resolved local BC starting from the lowest energy band, which corresponds to the \(\left(\left\vert xy\right\rangle +\left\vert xz\right\rangle +\left\vert yz\right\rangle \right)/\sqrt{3}\) state at (111) LAO/STO heterointerfaces. Figure...
Comparison to angle-resolved photoemission experiments31 and inelastic neutron-scattering32 have justified this procedure on the level of the single-particle spectra and static magnetic susceptibility. The excellent agreement we find in the present work supports the strategy also for the dynamic ...
It has a large dipole moment which gives rise to a relatively rapid spontaneous emission rate (12 ns) and pronounced Stark shift14,15, which has been also observed in spectrally resolved centers16,17. An energy level diagram of some of the latest models of the ground and excited state ...
