分子会坐在热电桌上吗？
Will molecules ever sit at the thermoelectric table?
摘要：
分子结包括一个或几个纳米长的小分子，化学连接到两个金属或半导体电极。它们最近已被确定为用于热电能量转换的材料/装置的有前途的候选者。分子有可能充当电流的尖锐能量过滤器，并且到目前为止可以胜过其他考虑用于热电能量转换的材料，从而提供热电迄今为止无法实现的广泛技术相关性。然而，在研究热电分子结的文献中，预测和演示之间存在明显的差距。这篇固执己见的评论旨在强调这种方法从基础研究过渡到可行技术所需的必要步骤。综述了分子结研究所依据的一些重要理论。
英文摘要：
Molecular junctions comprise small molecules on the order of one or a few nanometers in length, chemically attached to two electrodes of metal or semiconductors. They have recently been identified as promising candidates for materials/devices for thermoelectric energy conversion. Molecules have the potential to act as sharp energy filters for electrical currents and could outperform other materials considered for thermoelectric energy conversion so far, thereby providing a wide-spread technological relevance thermoelectrics could not achieve to date. However, there is a clear gap between predictions and demonstrations in the literature studying thermoelectric molecular junctions. This opinionated review seeks to highlight necessary steps needed for this approach to transition from fundamental research into a viable technology. Some important conjectures, on which the study of molecular junctions is based, are reviewed.
