量子点由磷化铟半导体构成，将它们喷涂在一张透明塑料片上，然后用另一张塑料片进行覆盖，最后将它们进行整体加热封装。
The dots, composed of a semiconductor called indium phosphide, are sprayed onto a transparent plastic sheet that is then covered with a second sheet. That done, the whole thing is heat-sealed.
然而很多半导体材料(semiconductor material)在加热时能够通过塞贝克效应(Seebeck effect)这种形式产生电势能(electric potential)，但是在碳中发生的塞贝克效应很微弱。
While many semiconductor materials can produce an electric potential when heated, through something called the Seebeck effect, that effect is very weak in carbon.
如果是一个电导体的一端被加热而另一端仍然是冷的，一个微小的电压就会在二者之间产生。
If one end of an electrical conductor is heated while the other is kept cool, a small voltage is created between the two.
