We report on the electrical and optical properties of microcrystal arrays obtained by depositing Ge on a deeply patterned Si substrate. Finite difference time domain simulations indicate that the faceted morphology and high refractive index of Ge mic

We report on the design and simulation of a waveguide-integrated Ge/SiGe quantum-confined Stark effect (QCSE) optical modulator based on the use of a Ge-rich SiGe relaxed buffer on a graded buffer as an optical waveguide. Despite the promising potent

The n-type doping of Ge is a self-limiting process due to the formation of vacancy-donor complexes (D _n V with n ⩽ 4) that deactivate the donors. This work unambiguously demonstrates that the dissolution of the dominating P _4 V clusters in heavil
