Abstract

The effect of strain and layer thickness on the transport properties of < 100 >, < 111 >, and < 110 > confined Si thin films is systematically investigated using the density functional calculation. The strain is uniformly applied to the plane perpendicular to the confined direction and the lattice along the direction is relaxed. Anomalously heavy effective mass, which is more than ten times of the strain-free bulk value, is found in the case of the < 111 > confinement with relatively large strain. Similar results are obtained for the < 110 > case. These heavy masses are attributed to the bulk property, where the two electron pockets, whose center is located about 0.84 Γ-X in the non-strained case, merge into one pocket under the relatively large strain.
