报告摘要

In the family of III–VI monochalcogenides M₂X₂ (M = gallium, indium; X = sulfur, selenide, etc.), the interlayer interaction and the electronic band edges share the contribution of the same chalcogenide atomic orbits. This makes quantum confinement and interlayer interaction play a subtle role in two-dimensional (2D) monochalcogenides crystals. In this report, we study the direction-resolved photoluminescence of 2D Ga₂Se₂ at various thicknesses. We observe that the in-plane dipole radiation survives, but out-of-plane dipole radiation fades at 2D limits.

会议简介

The 5th International Conference on 2D Materials and Technology was held in Suzhou, China, October 21-24, 2019. Prestigious scientists presented and stimulated discussions over some inherent topics of the ICON-2DMAT, including the Synthesis and Characterizations, Physics and Chemistry, Device applications, Theory and Modeling of 2D materials and heterostructures, etc. And, a special session related to the Vacuum Interconnected Nanotech Workstation (Nano-X) in Suzhou Institute of Nano-Tech and Nano-Bionics was be set up, which was dedicated to introduce a large scientific facility to 2D materials and technology. Specific forums and some other Symposia co-organized with preeminent academic publishers was be also established to foster academic and business networking.
