Engineering the Radiative Dynamics of Thermalized Excitons with Metal Interfaces

Here we analyze the emission properties of excitons in two metal structures: placed near a single metal (silver) interface and placed symmetrically at the center of a Fabry-Perot microcavity. The exciton is modeled as a point dipole and as an extended 2D dipole. With the momentum dependent emission rates for the extended exciton, we can also examine its temperature dependent behavior by applying a momentum distribution. We investigate the cases of a Maxwell-Boltzmann statistical distribution and a Bose-Einstein statistical distribution (since excitons form composite bosons). The dataset provided are the Mathematica codes used to generate the plots in our paper. The point dipole results are contained in the notebook files: Emission Rate 2, Multiple Interfaces, Multiple Interfaces_Par (1), and Multiple Interfaces_Perp. The extended exciton results are contained in the notebook files: Extended Exciton 2-3 and BE stats.本文针对两种金属结构中的激子(Excitons)的发射特性展开分析：一种是放置于单金属（银）界面附近的结构，另一种是对称置于法布里-珀罗(Fabry-Perot)微腔中心的结构。本研究将激子建模为点偶极子与扩展二维偶极子。借助扩展激子的动量依赖发射速率，我们还可通过引入动量分布，探究其温度依赖特性。本文研究了麦克斯韦-玻尔兹曼统计分布与玻色-爱因斯坦统计分布两种情形，原因在于激子属于复合玻色子。本数据集即为用于生成本文插图的Mathematica代码。点偶极子的计算结果存储于以下笔记本文件：Emission Rate 2、Multiple Interfaces、Multiple Interfaces_Par (1)以及Multiple Interfaces_Perp。扩展激子的计算结果则存储于Extended Exciton 2-3与BE stats笔记本文件中。
