RIBER 32 for As-III-based semiconductors
Using this equipment, layer structures can be built up for semiconductors based on group III arsenides [GaAs(N,Sb), InGaAs(N,Sb), AlGaAs(N,Sb)], with atomic resolution (individual atomic layers in various materials) and with highly precise control of flatness and thickness. This enables quantum well and quantum dot devices to be made.
The equipment allows many different devices to be developed, such as light emitters (LED, LASER, Single photon emitters), filters, modulators, diodes, transistors or light detectors. It is the basic equipment where material is made which is used in the remaining processes and, therefore, is the beginning of the entire manufacturing chain for any electro-optical device.
Apart from making light emitters and photodetectors, the equipment is highly suited for use in quantum communications, as it is capable of making light emitting and detecting structures that are essential for this type of communications. Depending on the type of materials used, its wave length in use extends from 620nm up to approximately 20 µm in the IR-visible.
Area of application: Electronics, Optics, Optoelectronics, Quantum communications.
The key advantage of growth with MBE is that its resolution is +/- 1 atomic layer (approximately +/- 5 nm) It has several systems for monitoring material quality in-situ. Amongst them, one of the highlights is RHEED (Reflection High Energy Electron Diffraction) which enables analysis of the crystal's growth facet while progressing and assessing its quality, growth speed and thickness, as well as detecting the appearance of quantum dots on the surface.
