    Transistors form the basic structure in every microchip.

    Can we say that the transistor is able to differ between two states of
    an electron?

    Can it be said that a transistor is fundamentally a device that is
    able to differentiate between two states of an electron?
  2. I wouldn't.
  3. Eep! Watch out.. Sounds like homework to me! ;-)

    (Please explain all answers concisely, but with as much detail as
    required. Writing in the margins or on the back will NOT be marked!)

    OK, lets's see here.

    Q1. Sure you can SAY that. You can say anything you want. It doesn't
    make it correct, though.

    Q1a. See above.

    Believe me it is not Homework.
  7. Okay, I believe you. But I have never heard of or thought of
    transistors in the terms you are using. Electrons in solids
    (especially semiconductors) have many possible states. Which two do
    you have in mind? I think of transistors as thermal devices because
    their collector current depends on the random (thermal) drift of
    charge carriers through the forward biased base region. Can any
    junction transistor have gain at absolute zero temperature?

    This is a _very_ interesting question. Does anybody know if semiconductors
    become superconductors at those temps? If they do, then it'd just be
    a short. If not, it'd be a very interesting experiment.

    But at absolute zero, there's no electron movement at all. Wouldn't
    this mean that there could be no charge transfer and hence no current?
    You'd end up with an infinite resistance dead short. :)

    Then, is one of the difficulties in reaching real absolute zero,
    the fact that everything would collapes into neutronium?
