a: Doping a semiconductor ~
b: adding a car pooling lane
What:
"Semiconductors can be turned into conductors by a process called doping. Doping a semiconductor is like adding a car pooling lane to an otherwise gridlocked motorway. Electrons from dopant atoms can move freely up and down the almost empty extra lane while the other electrons sit glumly in the traffic jam. "
