Making a Peltier cooler?

I wish to record my own Peltier cooling, there are metals that combine better than others or they are all equal how long are they different?

While there are differences: http://en.wikipedia.org/wiki/Thermoelectric_effect and kept cool, semiconductors, not metals. Bismuth telluride is one of the better materials: http://en.wikipedia.org/wiki/Bismuth_telluride uranium dioxide has some interesting possibilities: http://en.wikipedia.org/wiki/Uranium_dioxide # Semiconductor_properties Here are some other pairs: http://ixbtlabs.com/articles/peltiercoolers/ But it seems to me that if you have any questions, you do not have what it construct a useful device to take. But if you just build a demo unit or a science FAIR project, good luck.
