摘要

基于光子学的方法最近成为实现大规模实用量子处理器的有力候选。特别是近年来,二维(2D)材料由于其方便的片上集成等几个独特优势,已成为开发理想集成光源的有力候选者。本文研究了应变对发射波长和载流子寿命的影响。我们首先证明了应力源的几何形状可以调节应变量和发射波长。利用这种应变工程技术,我们证明了发射波长可以显著位移~10 nm,载流子寿命也可以被工程化~ 30%。

Light emission and engineered carrier lifetime in strained 2D materials towards developing wavelength-tunable integrated emitters
The photonics-based approach has recently become a strong candidate for realising a large-scale, practical quantum processor. Particularly in recent years, two-dimensional (2D) materials have become a strong candidate for developing an ideal integrated light source owing to their several unique advantages such as convenient on-chip integration. In this work, we study the effect of strain on the emission wavelength and carrier lifetime. We first show that the geometry of stressors can adjust the amount of strain and emission wavelength. Using this strain engineering technique, we demonstrate that the emission wavelength can be significantly shifted by ~10 nm while the carrier lifetime can also be engineered by ~30 %.
