他们能工作是因为像碲化铋这样的材料,如果在他们的一端比另一端热,那么内部会产生一个电势差,这可用于驱动外部电路中通过的电流。
They work because certain materials , such as bismuth telluride , generate an electrical potential difference within themselves if one part is hotter than another . That can be used to drive a current through an external circuit .

第三个目标、高效的设计,包括三明治式的结构,纳米级碲化铋在两个铜片之间,并封闭上面的铜片(一面覆盖吸光的氧化物),碲化铋则在真空中,铜片传导热量迅速到碲化铋。
The third objective , efficient design , involved sandwiching the nanostructured bismuth telluride between two copper plates and then enclosing the upper plate ( the one coated with the light-absorbing oxides ) and the bismuth telluride in a vacuum . The copper plates conducted heat rapidly to and from the bismuth telluride , thus maintaining the temperature difference .
