Outline of Final Research Achievements |
In this study, we have developed the growth technology of Sn-based group-IV alloy thin films to create novel non-thermal-equilibrium ultra-high Sn-content group-IV alloys that cannot exist in natural thermal equilibrium conditions. We have demonstrated the formation of ultra high-Sn-content GeSn epitaxial layers with Sn contents of 25-50% and a thicknesses of 10-100 nm using InP and GaSb substrates those have lattice constants larger than Ge. In addition, photoluminescence measurements revealed the photoelectric conversion properties of GeSn/GeSiSn stacked structures and multilayered GeSn nanodots/SiO2 structures.
