In practical terms, a low effective mass leads directly to high carrier mobility, favoring higher speed of transport and current carrying capacity.
42.
One remarkable property is that the effective mass can become " negative ", when the band curves downwards away from a maximum.
43.
Workers frequently go on strike in Russia, but aside from miners and energy workers they have yet to organize effective mass labor action.
44.
Additionally, the effective mass of holes in the valence band is changed to more closely match that of electrons in the conduction band.
45.
It was later shown by Yuan and Schaefer that the effective mass density needs to be changed to simulate multiphase flow more accurately.
46.
The bandedges and effective masses of the bulk materials and the nanostructures structures can be analyzed as a function of various strain conditions.
47.
Workers frequently go on strike in Russia, but aside from miners and energy workers, they have yet to organize effective mass labor action.
48.
In such complex materials there is no single definition of " effective mass " but instead multiple definitions, each suited to a particular purpose.
49.
The polaron concept was first proposed by Lev Landau in 1933 to describe an electron moving in a dielectric crystal where the effective mass.
50.
The " conductivity effective mass " of a semiconductor is also defined as the harmonic mean of the effective masses along the three crystallographic directions.
