I am struggling with the intuition of why I can't leave the gate only connected to the + terminal of a battery:

In my understanding, until equilibrium electrons would still flow towards the + battery terminal. This would still move the minority carriers towards the gate, and still create the channel?

Here is a drawing of what I had in mind: a MOSFET with the gate connected only to the + terminal.

  • $\begingroup$ If the + terminal had 3 H+ protons, then 3e- would move towards them ? $\endgroup$ – DDleo Sep 30 at 11:23
