The electron and hole mobility can be raised (or lowered) by carefully engineered mechanical strains. The strain changes the lattice constant of the silicon crystal and therefore the E–k relationship through the Schrodinger’s wave equation. The E–k relationship, in turn, determines the effective mass and the mobility.
