    Effect of gas–liquid–crystal transitions in oxygen clusters on electric and magnetic activity of localized states in In2O3–SrO ceramic

    It has been shown that the overlap of tails of the density of states of the valence and conduction bands leads to the formation of a “negative” gap in the In2O3–SrO ceramic with disordered structure and oxygen cl...
