The partial filling of the states at the bottom of the conduction band can be understood as adding electrons to that band. The electrons do not stay indefinitely (due to the natural thermal recoination) but they can move around for some time.The actual concentration of electrons is typically very dilute, and so (unlike in metals) it is possible to think of the electrons in the conduction
