Silicon Technologies

The EPSRC National Epitaxy Facility can provide III-V semiconductor structures grown on either silicon or germanium substrates, via molecular beam epitaxy. Our partners located at University College London, have developed growth techniques to enable a wide range of devices using III-V semiconductors on silicon, such as: InAs Quantum Dot lasers, infrared photodetectors and nanowires all grown directly on silicon substrates.

InAs/GaAs Quantum Dot Laser Monolithically Grown on Silicon Substrate

The facility has expanded to include group IV epitaxy and hybrid III-V/Group IV epitaxy enabling capabilities in, for example, silicon photonics.
