    • A method for forming a thermoelement for a thermoelectric cooler is provided. In one embodiment a first substrate having a plurality of pointed tips separated by valleys wherein the substrate is covered by a metallic layer, portions of the metallic layer is covered by an insulator, and other portions of the metallic layer are exposed is formed. The other portions of the metallic layer that are exposed are covered with a thermoelectric material overcoat. A second substrate of thermoelectric material is then fused to the pointed tip side of the first substrate by, for example, heating the back of the first substrate to melt the thermoelectric material overcoat or by passing current through the pointed tips to induce Joule heating and thereby melt the thermoelectric material overcoat.
    • 提供一种用于形成热电冷却器的热电偶的方法。 在一个实施例中,具有由谷分开的多个尖端的第一衬底,其中衬底被金属层覆盖,金属层的部分被绝缘体覆盖,并且形成金属层的其它部分被暴露。 暴露的金属层的其它部分被热电材料外涂层覆盖。 然后,通过例如加热第一基板的背面以熔化热电材料外涂层或通过使电流通过尖端来引起焦耳加热,从而将热电材料的第二基板熔合到第一基板的尖端侧,从而 熔化热电材料外涂层。
