Graphite-like (metal!) regions and diamond-like (dielectric!) regions in carbon nanostructures are very closely spaced. Based on this unique feature, a model of thermal emf produced due to the drag of electrons by ballistic phonons is developed and a model of thermal conduction during heat transfer through the graphite-like/diamond-like region interface is proposed. Experiments with a thermoelectric generator based on film carbon nanostructures are analyzed. Models of a thermoelectric generator based on a composite of a graphite-like matrix containing diamond nanoparticles and graphene impurities are proposed. These models both demonstrate the above-mentioned phenomena and predict the achievement of the maximum thermoelectric conversion efficiency.

基于碳纳米结构的热电效应和热电发电机:成就与展望

碳纳米结构中的类石墨(金属!)区域和类金刚石(电介质!)区域间隔非常近。基于这一独特的特征,开发了由于弹道声子的电子拖动而产生的热电动势模型,并提出了通过类石墨/类金刚石区域界面进行热传递过程中的热传导模型。分析了基于薄膜碳纳米结构的热电发电机的实验。提出了基于含有金刚石纳米颗粒和石墨烯杂质的类石墨基体复合材料的热电发电机模型。这些模型都证明了上述现象并预测了最大热电转换效率的实现。
