Ab Initio Study of Strain Effects on the Quasiparticle Bands and Effective Masses in Silicon

Figure 4

Contour plot of in the plane of the Brillouin zone for the lowest conduction band without strain (a) and with 3.0% uniaxial strain in the direction (b). The quasiparticle energies are given in eV and relative to the minimum of the band in each configuration.
