A reverse biased [PN Junction](PN%20Junction.md) - no current flows. Apply a positive voltage to the gate - repels positive carriers in the substrate - negative carriers accumulate under the channel (like a [Capacitor](Capacitor.md)).  --- # References [^1]: [vr-4602-wk01-sc01-transistors](../../Spaces/University/ELEC4602%20–%20Microelectronics%20Design%20and%20Technology/Lectures/W1/vr-4602-wk01-sc01-transistors.mp4)
