Abstract
  
    
Recently the study of novel heterointerfaces between complex oxides has been바카라 조작attractive바카라 조작because바카라 조작of바카라 조작its
peculiar physical properties at the interface which are not shown in bulk properties. In the heterointerfaces
of perovskites LaAlO3/SrTiO3 with a polarity discontinuity, the n-type metallic behavior had been measured
experimentally at the interface, contrary to insulating properties of two bulk materials.바카라 조작I바카라 조작will바카라 조작introduce바카라 조작our

For overcoming the energy crisis, such as the fossil fuels (oil, gas, coal) depletion and the global warming
by CO2, today, the renewable, alternative, and carbon-neutral energy systems are broadly바카라 조작studied바카라 조작in바카라 조작the

very important. In the field of energy storage, as one of good candidates for hydrogen storage,바카라 조작MgH2 has
been investigated, where the relevant defect species and their migration바카라 조작barriers바카라 조작have바카라 조작been바카라 조작determined.

oxides are investigated by the calculations of Seebeck coefficient and electrical conductivity.
