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.本研究针对两类金属结构中激子（exciton）的发射特性展开分析：一类为置于单金属（银）界面附近的激子，另一类为对称放置于法布里-珀罗（Fabry-Perot）微腔中心的激子。本研究将激子分别建模为点偶极子（point dipole）与扩展型二维偶极子（extended 2D dipole）。借助扩展型激子的动量依赖发射速率，通过引入动量分布函数，我们还可探究其温度依赖的演化行为。本研究分别考察了麦克斯韦-玻尔兹曼（Maxwell-Boltzmann）统计分布与玻色-爱因斯坦（Bose-Einstein）统计分布两种情形——因激子属于复合玻色子（composite bosons）。本次提供的数据集为用于生成本文插图的Mathematica代码文件。点偶极子模型的计算结果存储于如下Mathematica笔记本文件：Emission Rate 2、Multiple Interfaces、Multiple Interfaces_Par (1) 及 Multiple Interfaces_Perp。扩展型激子模型的计算结果则存储于Extended Exciton 2-3与BE stats两个Mathematica笔记本文件中。
