Holes in semiconductors

    I understand that holes are sites of missing electrons in the structure of a solid semiconductor. When there is a potential difference between the ends of a sample, electrons can move to fill the holes and in effect the holes move the other way to form an electric current.

    However, is the hole positive or negative charged?

    hole is regarded as positive charged. But holes just "lack" of electrons, they are not real particles.

    This should also have been posted in Atomic, Solid State, Comp. Physics forum.
