Microstructure and thermoelectric properties of thin foils of bismuth telluride alloys

摘要

Ultrarapid quenching processes have been extensively studied during the past few years, particularly for glasses. In the case of polycrystalline materials, the problem is slightly different. In this case, the microstructures botained by this process are very different from those obtaiined by normal cooling and they induce new physical proerties.
