摘要: 二维材料中存在多种类型的极化激元,包括等离极化激元(光子-电子耦合),声子极化激元(光子-声子耦合),激子极化激元(光子-激子耦合)等。这些极化激元模式可以突破光学衍射极限,实现宽光谱频率范围内(可见光到太赫兹)光场的纳米局域以及纳米光场的精确调控。在系列报告中,我将系统介绍二维材料极化激元学的研究进展,展示我们课题组在石墨烯、氮化硼、氧化钼、五氧化二钒等材料中发现的新奇光电物性,并对极化激元学未来应用进行展望。 |

*Title:Nanooptics with 2D materials |
*Reporter: Dr. Pablo Alonso Gonzalez *Time:5 pm in Beijing time on 27th Nov., 30th Nov., 1st Dec. 2023 *Place:Voov Meeting 411-633-2718 *Contact Person: Jiahua Duan 13811465455 |
*Abstract: The advent of two-dimensional (2D) materials and their extraordinary optical properties has allowed the visualization of nanolight in the form of electrically tunable (active) plasmon polaritons in graphene or low-loss phonon polaritons in h-BN or alfa-MoO3, introducing a very encouraging arena for scientifically ground-breaking discoveries. In these talks I will show our latest studies on both the visualization and control of nanolight in 2D platforms.

*Profile: Pablo Alonso-González holds a Distinguished Researcher position at the University of Oviedo (Spain) where he leads the Quantum Nanooptics Lab at the Department of Physics. He obtained his PhD degree in Physics from the Universidad Autónoma de Madrid (2009). From 2009 to 2015 he was post-doctoral researcher at the Nanooptics group at CIC nanoGUNE in San Sebastian (Basque Country, Spain). Alonso-González´s research activities are focused on materials science and nanophotonics with special emphasis on the study of the opto-electronic properties of novel 2D materials at the nanoscale. In 2014 he received the Spanish Royal Society of Physics (RSEF-BBVA) prize in the category of young experimental scientist, and in 2021 he was selected as a finalist for the Falling Walls Science Breakthroughs of the Year 2021 in Physical Sciences. In 2016 and 2022 he was awarded by the European Research Council (ERC) with a Starting and a Consolidator Grant project, respectively. |
