Abstract
The conduction band offset for strained Si1-x-yGexCy layers grown on Si(0 0 1) is estimated by considering separately the hydrostatic strain, the uniaxial strain, and the intrinsic chemical effect of Ge and C. Tensile-strained C-containing layers provide a conduction band offset ΔEc suitable for electron confinement. At given ΔEc introducing Ge in C-containing alloys allows us to reduce the strain, which should be beneficial to the thermal stability. With a view to n-channel field effect transistor (FET) application on Si substrate, the in-plane electron mobility in tensile ternary layers is calculated using a Monte Carlo transport simulation. The impact of alloy scattering is emphasized.
