11. This is usually done by using the electrons'effective mass in place of " m ". 12. Effective masses can be derived from band structure computations.13. She said cities with effective mass transit systems tend to have lower traffic fatality rates. 14. A lower carrier effective mass also favors increased tunneling current, a direct result of delocalization. 15. But aside from miners and energy workers, Russians have yet to organize effective mass labor action. 16. Normally, in a conductor, increasing electric field causes higher charge effective mass and thus slow down. 17. These include but not limited to bandgap, effective mass , and defect levels for different perovskite materials. 18. In most semiconductors, the effective mass of a hole is much larger than that of an electron. 19. So newspapers are re-emerging on a secular basis as a very effective mass media in local markets. 20. Such an electron with the accompanying deformation moves freely across the crystal, but with increased effective mass .
