Semiconductor Quantum Structures and Devices

Semiconductor Quantum Structures and Devices is a research topic within Atomic and Molecular Physics, and Optics. Science Explorer counts 87k research works in it since 1950. 14.0% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the physics and applications of quantum dot devices, semiconductor materials, and single-photon sources. It covers topics such as band parameters for III–V compound semiconductors, strong coupling in quantum dot–semiconductor microcavity systems, and the generation of entangled photons from single quantum dots. The research also delves into the electronic structure of quantum dots, electrically driven single-photon sources, and the development of near-optimal single-photon sources in the solid state.
