Enhancing elastic stress relaxation in SiGe/Si heterostructures by Si pillar necking

Isa, F.; Salvalaglio, M.; Dasilva, Y. A. R.; Jung, A.; Isella, G.; Erni, R.; et al. (2016)

We demonstrate that the elastic stress relaxation mechanism in micrometre-sized, highly mismatched heterostructures may be enhanced by employing patterned substrates in the form of necked pillars, resulting in a significant ...
From plastic to elastic stress relaxation in highly mismatched SiGe/Si heterostructures

Isa, F.; Salvalaglio, M.; Dasilva, Y. A. R.; Jung, A.; Isella, G.; Erni, R.; et al. (2016)

We present a detailed experimental and theoretical analysis of the epitaxial stress relaxation process in micro-structured compositionally graded alloys. We focus on the pivotal SiGe/Si(001) system employing patterned Si ...
