Title: Anis Attiaoui and Silicon-Compatible Quantum Heterostructures.

Introduction

Anis Attiaoui is an inventor associated with Menlo Park, California, and Corporation De L’École Polytechnique de Montréal. His work includes a patent for a quantum heterostructure designed to be compatible with silicon-based processing and technologies.

Latest Patents

Attiaoui is named on 1 patent: “Quantum Heterostructures, Related Devices and Methods for Manufacturing the Same.” The invention describes a stack of coextending germanium-tin (GeSn) buffer layers, each with a different tin content, topped by a quantum well. The well includes a highly tensile-strained layer containing at least one Group IV element, with strain of at least 1%.

The disclosed manufacturing method adjusts reactor temperature and varies the molar fraction of a tin-based precursor to form the GeSn buffer layers on a substrate. The quantum well is then formed over the stack. The approach aims to support quantum devices using processes compatible with silicon-based manufacturing.
