Compositional and Strain Dependence of Effective Masses in Strained GeSn Alloys: Efficient Calculation

Carrier effective masses under strain are vital for GeSn band engineering. Using well-established full-zone 30-band k · p and continuum elasticity theories, we calculate band-structure, density-of-states (DOS) and conductivity effective masses of Ge 1-x Sn x (0 ≤ x ≤ 0.2) under six strain modes from -1.5% c...
