A transistor it has in its composition a semiconductor material. That's the whole idea behind the transistor as a programmable switch, using a gate(drain) variable intensity to drive how much it gets opened. And if you increase the voltage that semiconductor becomes a conductor instead, hence the shortcut I was talking about - goo or no goo.
