Using a first-principles calculation, we systematically investigated the effective-mass anomalies in 〈111〉- and 〈110〉-confined Si thin films. The surface terminators, which correspond to the interface between the Si channel and the insulator in real devices, do not have a significant effect on the effective mass anomalies. The effective-mass behaviors as a function of the substrate thickness and the strain is qualitatively well explained by the extended effective-mass approximation using the bulk effective-mass along the confinement direction.
