CM,

For an NPN transistor in "common emiter" configuration.

I find that the voltage Vb, beyond threeshold voltage, which is actually attracting electron to travel to base region.

so according to my finding, the main thing is Vb, instead of Ib which responsible for attracting electron to travel from "Emitter region" to "Base region" which then get swept into "Collector region".

I still strongly believe that its Vb which control Ic.

Vb: Voltage at Base electrode


Your advice to reconcile this and the standard
Ic = beta*Ib is very appreciated
