Growth of graded quantum wells for THz polaritonics
(University of Waterloo, 2021-09-02)Rectangular quantum wells have long dominated the landscape of layered nanostructures. They exhibit a rich variety of physics and can be reliably grown with techniques such as molecular beam epitaxy. Rectangular wells ... -
Heterostructure development and quantum control for semiconductor qubits
(University of Waterloo, 2022-01-04)States of confined electrons in semiconductors are promising candidates for quantum bits with high controllability, scalability, and coherence. Particularly, spin quantum dots offer direct integration with the modern MOS ... -
InAs/AlSb Based Mid-Infrared QCL Growth and XRD Simulation
(University of Waterloo, 2016-08-24)In the past two decades, mid-infrared (MIR) quantum cascade laser (QCL) research has been rapidly developed and has resulted in an enabling platform for the remote sensing and metrology. QCL is designed by spatial confinement ... -
Molecular beam epitaxial growth of InSb quantum well heterostructures for applications in topological quantum computing
(University of Waterloo, 2021-09-09)The small effective mass, large Landé g-factor, and strong spin-orbit coupling of InSb make high-quality InSb quantum well (QW) structures particularly appealing for the experimental realization of Majorana bound states ... -
Molecular Beam Epitaxial Growth Optimization for Next Generation Optoelectronic Devices Based on III-V Semiconductors
(University of Waterloo, 2020-09-01)Molecular beam epitaxy (MBE) has been serving as the best tool for group III-V compound growths due to its capability of depositing epilayers with high single-crystalline quality, high purity and Angstrom-scale thickness ... -
Multi-level Control in Large-anharmonicity High-coherence Capacitively Shunted Flux Quantum Circuits
(University of Waterloo, 2019-04-05)Superconducting devices as quantum bits (qubits) are one of the most promising candidates for implementing a practical quantum computer. Over the last decade, quantum coherence times of superconducting qubits have been ... -
Optimization of MBE growth of a high-quality 2-Dimensional Electron Gas in InAs/AlGaSb material system for pursuing a top-down approach towards realization of topological qubits.
(University of Waterloo, 2020-09-04)Two-dimensional electron gas (2DEG) in InAs quantum wells grown on nearly lattice-matched GaSb substrates is an ideal platform towards the realization of topological quantum computing with Majorana fermions, due to its low ... -
Realization of atomically smooth defect free InGaAs/InAlAs superlattice on InP(111) substrate by molecular beam epitaxy
(University of Waterloo, 2021-07-15)InGaAs and InAlAs epilayers and superlattices were grown on rounded edge InP(111)A and InP(111)B substrates as well as on 0.45°, 1° and 2° misoriented InP(111)B substrates by Molecular Beam Epitaxy (MBE). Rounded edge ... -
Study of unintentional As incorporation into AlSb and interfacial layers within InAs/AlSb superlattices
(University of Waterloo, 2019-02-21)Highly strained interfaces may exist between indium arsenide (InAs) and aluminum antimonide (AlSb) layers grown by Molecular Beam Epitaxy (MBE). The composition and thickness of the interfacial layers strongly influence ...
