While this was a very interesting description of the electron flow in 2DEGs, I don't think it deals with my original question about transistor performance.

I am going to give a presentation on High Electron Mobility Transistors (the ones that use a 2 dimension electron or hole gas), and although I can find many detailed descriptions of the band structures and what causes the 2DEG's high mobility, I haven't found a clear description of the process...

I guess what I'm asking is this: Is it true that if you do this experiment in an accelerating spaceship you would get the same discrete states? And if the above is true, then you don't need a quantum theory of gravity to explain the results of the experiment. All you need to do is a quantum...

But there is a distinction between real gravity and an accelerated reference frame. Real gravity involves tidal forces which can be represented as the curvature of space-time. Also, even if this experiment involved tidal forces, I'm still not sure it would be evidence for a quantum theory...

In the Wikipedia article "Quantum Gravity", it claims that there is some experimental motivation for finding a quantum theory of gravity. In one of the experiments it cites, neutrons are found to jump between discrete quantum states in the Earth's gravitational potential, similar to the discrete...
