    • A method is provided for growing Si—Ge materials on Si(100) with Ge-rich contents (Ge>50 at. %) and precise stoichiometries SiGe, SiGe2, SiGe3 and SiGe4. New hydrides with direct Si—Ge bonds derived from the family of compounds (H3Ge)xSiH4-x (x=1-4) are used to grow uniform, relayed and highly planar films with low defect densities at unprecedented low temperatures between about 300-450° C., circumventing entirely the need of thick compositionally graded buffer layer and lift off technologies. At about 500-700° C., SiGex quantum dots are grown with narrow size distribution, defect-free microstructures and highly homogeneous elemental content at the atomic level. The method provides precise control of morphology, composition, structure and strain via the incorporation of the entire Si/Ge framework of the gaseous precursor into the film. The grown materials possess the required morphological and microstructural characteristics for applications in high frequency electronic and optical systems, as well as templates and buffer layers for development of commercial devices based on high mobility Si and Ge channels.

    • This invention teaches two new families of Si-based Ge/SnxGe1-x heterodiode and multiple quantum well (MQW) photonic devices: (1) band-to-band photodetectors, lasers, emitters, amplifiers and modulators for the 1.5 to 12 μm wavelength range; (2) intersubband photodetectors, lasers, emitters and modulators for 12 to 100 μm operation. The bipolar band-to-band devices have applications within the 1.5-2.2, 3-5 and 8-to-12 μm bands. The unipolar intersubband group has longwave infrared and terahertz applications. All strained-layer devices are grown a relaxed SnySizGe1-y-z buffer layer—a virtual substrate (VS) grown directly upon a silicon wafer by unique LT UHV-CVD. The VS provides a low-defect atomic template for subsequent heteroepitaxy and is an essential enabling technique for engineering tensile and compressive strain within the Ge/SnxGe1-x MQW by selecting the VS lattice parameter to be approx midway between the layer lattices.
