Yes, but the real question is whether it is voltage or current controlled.

Jes' trying to pull your chain, Kevin.
I have no problem with your explanation. Voltage causes charge movement. Simple and intuitively obvious.
The only problem I see is, except for a few pathological cases, everything electronic becomes voltage-controlled.
Diodes, transistors, FETs, MOSFETS, SCRs, Triacs, tubes, CRTs, relays, VOMs, DVMs, and so on. Regardless of how they function, they all fit in the same category.
So the term loses any meaning.

Ahmmm....:-)
That's trivial. Unless the device is magnetically, operated, its voltage control. As I keep noting, F=q(E + vxB). If one wants to get charge (collector) to *move* (change its motion) one must apply a force.
Indeed:
"Dr Hofer explains: "Our experiments demonstrate that we can control the current through a single molecule by charging a single atom on a silicon surface, while all surrounding atoms remain neutral" "
One could split hairs and argue that it is charge since, it is charge that is producing the electric field. Ultimately, all electro-magnetic effects are caused by charge.
