Latest Patents

Assali is associated with 1 patent, titled “Quantum Heterostructures, Related Devices and Methods for Manufacturing the Same.” The invention describes a quantum heterostructure built from coextending germanium-tin (GeSn) buffer layers, each with a different tin content. A quantum well extends over the buffer-layer stack and includes a highly tensile-strained layer containing at least one group IV element, with strain of at least 1%.

The patent also describes a manufacturing method that adjusts reactor temperature and varies the molar fraction of a tin-based precursor to form the GeSn layers on a substrate. The quantum well is then formed over the stack.
