| Title |
Mobility gap and anomalous dispersion |
| Date |
1973-09 |
| Description |
It is shown that anomalous dispersion of quasiparticles leads to nonpropagating states. Therefore regions of anomalous dispersion define a sort of "mobility gap." Using the coherent-potential approximation, we calculate the conditions for obtaining such a mobility gap in a disordered binary alloy. Just outside the mobility edges located at ωc the mobility vanishes as lω-ωcl. |
