A Schottky diode is a unipolar device. If a P-type Schottky diode is fabricated on an N-type Schottky diode, can we make a PN-junction diode and a PNP transistor?

  • Don't understand the question completely. Perhaps make a sketch... Is that sketch similar to the first one here: https://en.m.wikipedia.org/wiki/Schottky_transistor ? – tobalt Dec 15 '22 at 08:10

No you cannot make a pure silicon PN out of a Schottky PN as the latter has one layer metalized and a lower threshold . No you cannot make a PNP out of 2 diodes, But you can make a weak and strong diode pair out of a PNP with a common N.
