Is Diode Unipolar or Bipolar?
According to Some Sources, Diode Is a Bipolar Device Since It Has Both Electrons and Holes as Carriers. However According to Some Other Sources, Diode Is a...

Subsequently, one may also ask, what is bipolar and unipolar device?
As their name implies, Bipolar Transistors are “Bipolar” devices because they operate with both types of charge carriers, Holes and Electrons. The Field Effect Transistor on the other hand is a “Unipolar” device that depends only on the conduction of electrons (N-channel) or holes (P-channel).
Beside above, why FET is called a unipolar device? All FETs can be called UNIPOLAR devices because the charge carriers that carry the current through the device are all of the same type i.e. either holes or electrons, but not both. This distinguishes FETs from the bipolar devices in which both holes and electrons are responsible for current flow in any one device.
Beside this, what is bipolar diode?
Diodes are bipolar consisting of p and n junction where electrons and holes both are responsible for conduction in diode. ? Given figure is of npn bjt (formed by sandwiching of two pn junctions) where electrons and holes both responsible for conduction! That's why they are called bipolar!
Why diode is non linear device?
A nonlinear device is a device which does not have a linear input/output relation. In a diode, for example, the current is a non-linear function of the voltage. So, we can say a diode has a variable resistance. Since a diode has a variable resistance, it is a non-linear device.
