To clarify.. Consider a semiconductor with a relatively "small" band gap. Electrons require less energy to "move", correct? So if you had an element with a band gap significantly smaller than that of silicon, it would require less voltage to move the same electrons, and thus less energy is...

Does antimatter (negative matter) have "negative mass"? If not, why is this so suspected? And could anything theoretically have negative mass?

Sorry, I'm not the most well versed in physics. I was under the impression that the smaller band gap of silicon made it a "better" semiconductor (ie better suited for computing) at room temperature at Earth's atmospheric pressure, be that through bonding properties or otherwise. Maybe you can...

Might be an easy question (or not). What determines the band gap of an element? As far as I know, silicon is the most efficient single-element semiconductor because of it's small (but nonzero) bandgap. Next (as far as I know) is Selenium. I'm aware there are more efficient compounds, but...
