告知人介绍

Dr. Lidong Sun, Associate Professor at the Institute of Experimental Physics of Johannes Kepler University Linz in Austria. His research interest is focused on the fundamental understanding and the precise control of the growth of thin films and nano-structures on solid surface using real time in-situ optical spectroscopy and microscopy.

 

孙立东院士为美国林茨约翰开普勒大学实验物理研究所副教授,人家研究兴趣集中在使用实时原位光谱和显微术实现对固体表面薄膜和纳米结构生长的基本功理解和规范控制,在采取光学探针,气温和可变温度扫描隧道显微镜(STM)和激光显微镜/激光扫描显微镜表征固体表面和薄膜、表的物理吸附和化学吸附、吸附层的组织和人类学、低维系统中的相变以及纳米结构表面的筹措和特点等方面成果显著。不久前,在Phys. Rev. Lett.Appl. Phys. Lett.等刊物上发挥50多篇高水平科研论文,并在国际会议宣读论文40余次。

 

告知内容简介

Differential optical spectroscopy represents a group of versatile techniques for probing surface and interface structure.  These techniques are surface sensitive, non-destructive, not restricted to vacuum conditions and therefore provide significant advantages over conventional surface analysis techniques.  Consequently, these methods are very suitable for the in-situ studies of surface processes occurring under various environmental conditions.

In this talk, the measurement principle will be first introduced. The second part of the talk will be devoted to discussing their application in monitoring and precise control of the growth a nano-structures including metal clusters, organic thin films and 2D transition metal dichalcogenides.  Finally, the new application of the fluorescence microscopy as an in-situ probe for real time monitoring of the growth of organic thin films will also be presented.

差分光学光谱仪是一组用于检测表面和规模结构的军用技术。那些艺术是外部敏感的,非破坏性的,不限于真空条件,具有优于传统表面分析技术之明确特点。特殊适合于对在各种条件条件下发生之外部过程的进展原位研究。

在资本报告中,名将首先介绍差分光学光谱仪测量原理,下将致力于讨论该技术在检测和规范控制纳米结构(包括金属簇,近代史薄膜和2D联网金属二硫化物)的采用。末了,还将介绍荧光显微镜作为原位探针实时监测有机薄膜的发育的新进展。
