Optical absorption spectra of single crystals of the ferromagnetic semiconductor VBO3 are studied at high pressures up to 70 GPa achieved in a diamond-anvil cell. An electronic transition accompanied by sharp changes in the optical parameters and a decrease in the optical gap from E 0 = 3.02 eV...
An investigation of the $4s \leftarrow 3p$ electronic transition in weakly bound binary complexes of the Al atom with Ne and several molecules ($H_{2}$, $D_{2}$, $N_{2}$, $CH_{4}$) is reported. In contrast with the higher excited Al atomic states where the interactions are all...
Small but nonzero dipole transition moments are obtained for short internuclear distances for the transitions from the 1(I) state, which correlates with the metastable3P2state of Ar (in ArHe) or Ne (in HeNe). The radiative lifetime of the 1(I) state of HeNe (estimated from the vertical...
Heat in electronic devices is normally dissipated via cooling. Here the authors engineer the thermal dynamics of the Mott transition and dynamical thermal interactions with the substrate to enable neuromorphic computing in a NbOx-based device. Gwangmin Kim , Jae Hyun In & Kyung Min Kim Article ...
The intensity of a broad intense band at around 20,500cm 1 in the optical absorption spectra of all color zones of the sample is proportional to the product of Ti- and Fe-concentrations and herewith proves its attribution to electronic Fe 2+ /Ti 4+ IVCT transition. The band is strictly ...
The agreement of the ground-state combination differences with those obtained from the A II, B Σ-X Σsystems show that the band is the 0-0 band of a transition A' II-X Σin PtC. Constants for A' (PtC) are as follows: T= 13195.67 cm, B= 0.5038 +/- 0.0002 cmD= (0.55 +/- ...
Electronic structure of the transition metal ions in LiCoO2, LiNiO2 and LiCo0.5Ni0.5O2 - ScienceDirect We studied the electronic structure of the transition metal ions in LiCoO 2 , LiNiO 2 and LiCo 0.5 Ni 0.5 O 2 . The experimental technique used in the stu... LAM A,MA B,ECA A,.....
In cubic nanocrystalline as well as polycrystalline Y 2O 3:Eu 3+ prepared by combustion, the radiative transition rate of 5D 1– 7F 1 and the nonradiative relaxation rate of 5D 1– 5D 0 were obtained by measuring the temperature-dependence of emission intensity and lifetime. The results ind...
