Physics of Quantum Rings (NanoScience and Technology)

This book, now in its second edition, introduces readers to quantum rings as a special class of modern high-tech material structures at the nanoscale. It deals, in particular, with their formation by means of molecular beam epitaxy and droplet epitaxy of semiconductors, and their topology-driven electronic, optical and magnetic properties. A highly complex theoretical model is developed to adequately represent the specific features of quantum rings. The results presented here are intended to facilitate the development of low-cost high-performance electronic, spintronic, optoelectronic and information processing devices based on quantum rings.

This second edition includes both new and significantly revised chapters. It provides extensive information on recent advances in the physics of quantum rings related to the spin-orbit interaction and spin dynamics (spin interference in Rashba rings, tunable exciton topology on type II InAs/GaAsSb quantum nanostructures), the electron-phonon interaction in ring-like structures, quantum interference manifestations in novel materials (graphene nanoribbons, MoS₂), and the effects of electrical field and THz radiation on the optical properties of quantum rings. The new edition also shares insights into the properties of various novel architectures, including coupled quantum ring-quantum dot chains and concentric quantum rings, topologic states of light in self-assembled ring-like cavities, and optical and plasmon m.odes in Möbius-shaped resonators.

這本書是第二版，介紹了量子環作為一種特殊的現代高科技納米級材料結構。它主要討論了通過分子束外延和滴狀外延的方法形成量子環的過程，以及它們在電子、光學和磁性方面的拓撲驅動特性。書中提出了一個高度複雜的理論模型，以適當地描述量子環的特殊特徵。這裡介紹的結果旨在促進基於量子環的低成本高性能電子、自旋電子、光電子和信息處理設備的發展。

這本第二版包含了全新和顯著修訂的章節。它提供了關於量子環物理的最新進展的廣泛信息，涉及自旋-軌道相互作用和自旋動力學（Rashba環中的自旋干涉，可調節的類型II InAs/GaAsSb量子納米結構上的激子拓撲），環狀結構中的電子-聲子相互作用，新材料中的量子干涉現象（石墨烯納米帶，MoS2），以及電場和THz輻射對量子環光學特性的影響。新版還提供了有關各種新型結構特性的見解，包括耦合的量子環-量子點鏈和同心量子環，自組裝環狀腔體中的光拓撲態，以及Möbius形狀諧振器中的光學和等離子體模態。
