Abstract

In Si/Si_1-xGe_x/Si(100) heterostructure patterned into stripe shape with 〈110〉 direction, strain control of capping Si and Si_1-xGe_x layers is investigated. The Raman scattering analysis of the stripe patterned Si/Si_1-xGe_x/Si(100) heterostructure indicates strain relaxation in Si_1-xGe_x layer and introduction of tensile strain into capping Si layer by submicron stripe patterning. It is found that the effect of heat-treatment (750°C, 3 h) on the strain relaxation in Si_0.6Ge_0.4 layer of stripe has a negligibly small. The metal-oxide-semiconductor capacitor and photoluminescence measurements for strain controlled stripe patterned Si/Si _1-xGe_x/Si(100) heterostructure shows the change of energy band structure. copyright The Electrochemical Society.
