摘要

本讲座将回顾我们最近在导电氧化物和金属氮材料的非线性和发射特性方面的研究。本文将介绍一种利用原子层沉积(ALD)技术制备掺铝氧化锌(AZO) ENZ薄膜的增强方法。然后，我将讨论利用简并泵浦-探针光谱技术在不同泵浦影响和激发角度下，观察到AZO和ITO ENZ薄膜中热电子的异常非线性时间动力学和增强的光学非线性。最后，我将首次全面研究放置在ENZ薄膜附近的二维材料的光致发光及其对材料损失的依赖，以及这些发射体在ENZ范围内随激发波长的光谱响应。这项工作得到了美国国家科学基金会(资助号:1752295)和AFOSR-AOARD (FA2386-18-1-4099)的部分支持。

Enhancement of optical nonlinearity and spontaneous emission in nano-engineered epsilon-near-zero materials

This talk will review our recent studies on the nonlinear and emission properties of conducting oxide and metallic nitride epsilon-near-zero (ENZ) materials. I will present a method to engineer the field intensity enhancement of the Al-doped zinc oxide (AZO) ENZ thin films synthesized by atomic layer deposition (ALD) technique. I will then discuss the observation of abnormal nonlinear temporal dynamic of hot electrons and enhanced optical nonlinearity in AZO and ITO ENZ thin films under different pump fluences and excitation angles using a degenerate pump-probe spectroscopy technique. Finally, I will present the first comprehensive study of photoluminescence from a 2D material placed near ENZ films and its dependence on the losses of materials, as well as the spectral response of such emitters with excitation wavelengths across the ENZ regime.
