梅德维德瓦(Medoedva)等人提出了一种以Cu+Fe合金为一电极的高灵敏度低温热电偶。大家知道,像金合金那样,由于康多(Kondo)效应,含有少量3d过渡金属的铜合金在低温下有很高的热电势。产生高热电势的一个必要条件是合金中不存在其他杂质,这些杂质能够抑制添加的3d金属对热电势的贡献。 Medoedva et al. Proposed a high sensitivity, low temperature thermocouple with an electrode made of a Cu + Fe alloy. As we all know, due to the Kondo effect, copper alloys containing a small amount of 3d transition metal have a very high thermopower at low temperatures, like gold alloys. A necessary condition for generating a high thermal potential is that no other impurities are present in the alloy and these impurities can suppress the contribution of the added 3d metal to the thermoelectric power.
