Electronic and vibrational hopping transport in boron carbides

摘要: General concepts of hopping‐type transport and localization are reviewed. Disorder, electronic correlations atomic displacements, effects ignored in band structure calculations, foster charge carriers. Examples given that illustrate the efficacy these producing localization. This introduction is followed by a brief discussion relation between The fundamentals formation, localization, hopping small polarons and/or bipolarons then described. Electronic boron carbides presented as an example adiabatic bipolarons. Finally, notion vibrational introduced. high‐temperature thermal diffusion potential application this idea.
