Dislocation Filter Based on LT-GaAs Layers for Monolithic GaAs/Si Integration
Nanomaterials, 2022 The use of low-temperature (LT) GaAs layers as dislocation filters in GaAs/Si heterostructures (HSs) was investigated in this study. The effects of intermediate LT-GaAs layers and of the post-growth and cyclic in situ annealing on the structural ...

Low-noise GaAs quantum dots for quantum photonics [PDF]
Nature Communications, 2020 Quantum dots are both excellent single-photon sources and hosts for single spins. This combination enables the deterministic generation of Raman-photons—bandwidth-matched to an atomic quantum-memory—and the generation of photon cluster states, a resource

Characterization of Gaas/Si/GaAs Heterointerfaces [PDF]
MRS Proceedings, 1989 ABSTRACTTransmission electron microscopy of GaAs grown on Si for metal-semiconductor-metal photodetectors is presented in this paper. Two kinds of samples are compared: GaAs grown on a 15 Å Si epilayer grown on GaAs, and GaAs grown at low temperature (300°C) on Si substrates.
