Homework Help: Nanowire-based logic circuits

  1. Feb 5, 2008 #1
    In the picture below there's a circuit made of nanowires. I know that every junction acts as a diode, which can either have an infinite resistance or be set to conduct from vertical to horizontal wires.

    Below is also a solution for how to set the circuit to act as an AND-port.

    But I don't get it. Could someone possibly explain this behaviour to me?

    Edit: I apologize if this post isn't where it should be. This thing is part of a physics course, but I guess it could very vell fit in the Engineering, Computer Science, & Technology section of the forum.
