Seeing the positive charge of holes


Hence, the holes really do act like positively charged particles.


  1. That's pretty cool! I think physics classes especially could benefit from more visualization technology. Right now we rely on students to be able to imagine the correct pictures and make the correct logical leaps. A visual simulation instantly gets the correct picture across, much better than a string of words does.

  2. I've never thought about using a magnetic field to influence electron/hole motion in a solid before. Are the electrons attracted to collide with the edges?

    I'm reading Feynman Vol. II now. I love it how he derives the Aharonov-Bohm effect before introducing Faraday's law. :)
