| 31. | Wachs pointed to several trends : Job growth is greatest in low-density suburbs, where there is no cost-effective mass transit.
|
| 32. | The temperature dependence of the oscillations reveals that the carriers have a non-zero cyclotron mass, despite their zero effective mass.
|
| 33. | Physical parameters such as the bandgap and effective mass can also be obtained from the computed E ( k ).
|
| 34. | Workers strike frequently in Russia, but aside from miners and energy workers they have yet to organize effective mass labor action.
|
| 35. | He predicted existence of new ( additional, or Pekar ) light waves due to a small effective mass of electronic excitons.
|
| 36. | This is in contrast to deep level donors where the short range potential determines the energy levels, not the effective mass states.
|
| 37. | In practice, the effective mass extracted in this way is not quite constant in temperature ( does not exactly vary as ).
|
| 38. | In any case, if the band structure has the simple parabolic form described above, then the value of effective mass is unambiguous.
|
| 39. | From the analysis of the Shubnikov de Haas experiments, one can deduce the effective mass and the quantum lifetime of composite fermions.
|
| 40. | Certain III-V compounds such as GaAs and InSb have far smaller effective masses than tetrahedral group IV materials like Si and Ge.
