但实际上，电子在这种传导带中存在两种形态。

But in fact, an electron in the conduction band can be in one of two states.

在传导带，它会占据所能找到的最低能级（比如说右边这个）。

In the conduction band, it will occupy the lowest-energy state it can find (right-hand well).

当一个电子跃迁到传导带，它会在价带留下一个“凹陷”。

When an electron leaps into the conduction band, it leaves behind a hole in the valence band.
