Hello everybody:
It is known that point contact diodes were an antecedent of PN junction diodes.
I have read that they got their rectification properties from the fact that the metal in the point doped the semiconductor and formed a PN junction.
However, it is known that you can rectify with a metal-semiconductor junction, so I have not a good feeling about this explanation.
Is it possible that the configuration of a semiconductor with a point contact in a side and an ohmic contact in the other, have rectifying properties by itself?
I was trying to figure out if this could be possible, to no avail. I would like to hear to somebody who know about this thing by experience.
