I'm trying to understand how the P-N junction works. I understand how it behaves, but I'm not sure if that is all there is to know, because I'm not sure what the doped semiconductors are on their own. They are always mentioned in context of P-N junctions.
But what are their properties on their own? Is it that on their own, they are basically just semiconductors? And doping them doesn't change how they are on their own, but only how they behave when used in P-N junctions?
Would it make sense to think of doping as of adding some new property that wasn't there before? Kind of like magnetising, which also doesn't just tune properties, it basically creates a new property by changing the composition of the material.
