This is a Tesla Valve. It works by diverting liquid or gas back on itself when it is flown in one direction and allowing a smooth flow in the other direction.
Can the same concept be used to create a semiconductor? Why?

It would perhaps be more reasonable to think of a Tesla valve as a poor facsimile of a diode than to attempt to think of how to make a semiconductor function like a Tesla valve. A Tesla valve is quite leaky and it's main advantage is the lack of moving parts and perhaps fast response. A diode also has no moving parts and within reason and within your budget, it can be arbitrarily not leaky, arbitrarily fast, etc. To justify making a semiconductor that used the same principles as a Tesla valve, you would have to find some parallel for it's operating principle that would have some advantage.

I 'suspect' that you (just maybe) may be able to achieve something like this effect using thermionic emission and charged structures. Nothing as "fine" as the 'Tesla valve' probably, but something that bends electron streams in curved paths in one direction and accelerates them in the other. I (idly) wonder if there is anything in a Magnetron design that may be bent (pun noted) to this function.

No. The design of the Tesla valve requires a material which has inertia (so that the "slanted" paths are preferred for backflow), and which behaves as a viscous fluid (so that the pressure of the reversed backflows can obstruct forward flow). Neither of these is applicable to the movement of electrons within a conductor.

I'd agree on the absence of viscosity for electrons, though their inertia is real enough. Surface tension and molecular attraction (not the apparently similar Coanda effect) are required for the fluid to stick to the inclined walls, also absent from electrons.
