Abstract

Heteroepitaxial integration of III-V and Si has been researched for many years since the Si is the prevalent platform and III-V can be used for light emitting source (i.e., direct bandgap) [1]. Although vertical InAs nanowires (NWs) growth on Si substrate (11.6% lattice mismatch) without catalysts and patterning has been demonstrated by several groups, [2, 3], direct heteroexpitaxial growth of ternary InxGa1-xAs nanowires hasn't been systematically studied yet, in spite of its important spectral coverage in the near infrared range. In this paper, we report the one-dimensional heteroepitaxial growth of dislocation free InxGa 1-xAs nanowires on silicon (111) substrate in the entire composition range and demonstrate monolithically grown axial p-n junction tandem solar cells consisting of InxGa1-xAs NWs on Si with an efficiency that well exceeds the planar Si single junction solar cell fabricated using identical process.
