Research of Quantum Nanophotonics Based on Low-dimensional Semiconductors

During the last decade, low-dimensional semiconductors have been studied as some of the most interesting subjects in solid-state physics because they show unique electronic and optical properties caused by the quantum confinement effect. Due to their unique properties, low-dimensional semiconductors such as quantum dots (0D), quantum wires (1D), and quantum wells (2D) have been utilized for a wide variety of electronic and photonic device applications. This article presents the characteristics of the low-dimensional semiconductors and their quantum photonic applications, such as nanoscale lightemitting devices, single-photon sources, and exciton-polariton lasers.
