What is wrong with this picture

Well, let's look at the correct
version: |

In k-space the only possible states for electrons
and holes are right on the dispersion curve. An electron just somewhere as in
the wrong picture, would have a combination of energy E and
k-vector (or, same thing, momentum) that simply does not
exist. |

|
Of course, by drawing it 100 %
correctly, there would be so many things at the same point (e.g. tip/end of
arrows, symbol for hole, dispersion curve) that the drawing becomes hard to
"read". |
