The carrier velocities are simulated in the … WebIn the case of alloy materials the temperature dependent saturation velocities are calculated first using ( 3.134 ). For an alloy the model suggests a quadratic interpolation between the saturation velocities for electrons of the basic materials (A and B) depending on the material composition . In case of holes a linear interpolation is assumed.
