This book was released on 2019 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: InAs/GaAs quantum dots (QDs) and quantum dot molecules (QDMs) are self-assembled semiconductor nanostructures that can trap a single electron or hole in a 3-D potential-well. Grown by molecular beam epitaxy (MBE), they have excellent optical qualities that can be used in applications for quantum information processing and quantum computing. Specifically, hole spins in a single QD/QDM have longer decoherence time than electron spins due to the lack of hyperfine interaction, making hole spins a great qubit candidate. However, many challenges such as QD growth, device integration, and spin manipulation inhibit the scalability of a hole-spin-based quantum information platform. A deeper understanding of the hole spin physics and the QD/QDM material system is needed to advance device engineering opportunities.

This book was released on 2011-12 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: In semiconductors, free charge carriers such as electrons and holes can be confined in all three dimensions in nanometer sized regions called quantum dots (QDs). QDs are convenient tools to gain detailed insight into the single photon-single emitter interaction and they serve as optical probes to study semiconductor physics at the nanoscale. The spin state (spin-up or spin-down) of a trapped QD electron or QD hole is a promising candidate as a computational unit for quantum information processing (QIP), the application of quantum mechanics to information processing. QIP promises immense computational power and secure communication. This work focusses on the optical spectroscopy of single InGaAs QDs and it addresses major challenges of using QD spins for QIP.

Download or read book Self Assembled InGaAs GaAs Quantum Dots written by Mitsuru Sugawara and published by Academic Press. This book was released on 1999-03-22 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is concerned with the crystal growth, optical properties, and optical device application of the self-formed quantum dot, which is one of the major current subjects in the semiconductor research field. The atom-like density of states in quantum dots is expected to drastically improve semiconductor laser performance, and to develop new optical devices. However, since the first theoretical prediction for its great possibilities was presented in 1982, due to the difficulty of their fabrication process. Recently, the advent of self-organized quantum dots has made it possible to apply the results in important optical devices, and further progress is expected in the near future. The authors, working for Fujitsu Laboratories, are leading this quantum-dot research field. In this volume, they describe the state of the art in the entire field, with particular emphasis on practical applications.
