The growth of heteroepitaxial planar fully strained SiGe layers with high Ge concentration
and large thickness enables tailoring electronic properties for enhanced transport properties …

III-V solar cell cost reduction and direct III-V/Si integration can both be realized by depositing
a thin layer of high-quality Ge on relatively low-cost Si substrates. However, direct epitaxial …

Performance predictions and optimisation strategies in current nanotechnology-based
photovoltaic (PV) require simulation tools that can efficiently and accurately compute optical …

We report on the epitaxial growth of Ge virtual substrates directly on Si (001) and on different
porosity porous silicon (pSi) buffers. Obtained results indicate that Ge grown on low porosity …

A novel method for incorporating the effects of luminescent coupling and photon recycling in
numerical simulations of planar devices is described. The carrier generation is incorporated …
