Do you know any examples of semiconductor junctions being used in biological processes? It would be hilarious to me if there was a bacterium out there that just ”invented” a transistor or a diode for some silly reason.
Paper on biological diodes https://arxiv.org/pdf/1706.00383.pdf but it doesn't use semiconductors, but ion transport (calls it iontronics instead of solid state electronics)
Indeed the ion channels used by nerves and muscles to send electrical signals are, like, one-way valves for ions
