The delocalization of atoms associated with tunneling converts impurity atoms and vacancies into the distinctive quasiparticles known as impuritons and vacancyons, respectively. These quasiparticles determine the properties of quantum crystals. Thermal properties. In most solids, the specific heat C at ...
A dependency of its electrical conductivity on P(O2) was discussed along with a change in concentration of oxygen vacancies and mixed valences. select article High temperature properties of the n = 2 Ruddlesden–Popper phases (La,Sr)3(Fe,Ni)2O7−δ Research articleAbstract only H...
Oxygen vacancies and N-doping in organic–inorganic pre-intercalated vanadium oxide for high-performance aqueous zinc-ion batteries Pre-intercalation of metal ions into vanadium oxide is an effective strategy for optimizing the performance of rechargeable zinc-ion battery(ZIB)cathodes.H...

Our energy generation and other industrial processes on which our current lifestyle is based cause significant environmental impacts. Some widely employed industrial processes are major contributors to CO2emissions. A prime example is ammonia production, which represents a high energy consumption, utilizes ...
The Si/C atomic ratio is normally one; however, vacancies can change it. Table 1 shows SiC polytypes’ lattice constants, electron mobility, bandgap, and more. The difference in bulk energy between SiC polytypes is 0.99 meV.atom−1, according to abinitio calculations. Nishino et al. [10]...

Within a polycrystal, obstacles to phonon motion include point defects—vacancies, interstitials, impurities—line defects such as dislocations, surface defects such as grain boundaries, interfaces, and free surfaces, and what could be termed three-dimensional defects such as precipitates. Recently, the...

Introducing a low-valent cation as a dopant in the oxide creates oxygen vacancies, which serve as pathways for oxygen ions. According to existing literature, dense electrolytes typically exhibit an open circuit voltage (OCV) slightly above 1V when hydrogen is used as the fuel source [46]. ...
Hence, they contain less amounts of interstitial oxygen in the rock salt layers and more oxygen vacancies in the perovskite layers. As a result, the oxygen diffusiv- ity of the higher-order RP phases is lower compared to that of the first-order RP phases (Figure 22). For these materials...
