The thermodynamic calculations of dissociation of LiAlO2 and LiGaO2 as function of temperature and oxygen pressure are presented. It has been found that LiGaO2 evaporates congruently at the melting point under the oxygen pressure equal to 1 · 10—5 atm. LiAlO2 evaporates incongruently, the equilibrium oxygen partial pressure at the melting point is equal to 9.6 · 10—5 atm and the partial pressure of Li and Al oxides decrease with increasing of oxygen pressure. 相似文献

Resonance magnetic tunneling in heterostructures formed by graphene single sheets separated by a hexagonal boron nitride barrier and bounded by two gates has been investigated in a strong magnetic field, which has allowed observing transitions between spin- and valley-split Landau levels with various indices belonging to different graphene sheets. An unexpected increase with the temperature in the interlayer tunneling conductance owing to transitions between the Landau levels in strong magnetic fields cannot be explained by existing theories. 相似文献

The aim of this brief report is to study the behaviour of sheath structure in a multi-component plasma with dust-neutral collisions.
The plasma consists of electrons, ions, micron size negatively charged dust particles and neutrals. The sheath-edge potential
and sheath width are calculated for collisionally dominated sheath. Comparison of collisionless and collisionally dominated
sheath are made. 相似文献

The plasma treatment of polyethylene (PE) gives a specific pattern of thermoluminescence (TL). The qualitative difference between the TL curves of PE after plasma treatment and the curves for radioluminescence appears to be due both to specific features of the plasma treatment (attack on the surface of the sample and the unavoidable effect of photobleaching) and to the particular structure of the surface of the polymer (the existence or formation in the surface layer of special low-molecular structures). TL after plasma treatment can therefore be used to investigate the surface structure of polymers.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 8, pp. 1742–1744, August, 1990. 相似文献
