2016年9月28日，澳大利亚国立大学Hoe Tan应何老师邀请来紫金光电进行学术交流，并做了题为“Semiconductor nanowires for optoelectronic and energy applications”的学术报告。

Hoe Tan教授的报告首先介绍了他们实验室在纳米线制备上的被称为气液固机制的工艺，利用金属纳米颗粒催化纳米线的生长。他们利用这种工艺，生长了GaAs，InGaAs,InP和GaAsSb纳米线，并介绍了这些纳米线的光学和结构性质，比如纳米线的非均匀性，晶体结构，载流子寿命和偏振效应等等。之后，Hoe Tan教授介绍了他们利用这些纳米线制作的器件，比如纳米线激光器，光探测器，太阳能电池。

报告结束后，相关同学就报告中的问题与Hoe Tan教授进行了交流讨论。

Hoe Tan教授背景介绍：

Prof. Tan is currently the Head of the Department of Electronic Materials Engineering at the Research School of Physics and Engineering, The Australian National University. He received his B.E. (Hons) in Electrical Engineering from the University of Melbourne in 1992, after which he worked with Osram in Malaysia as a quality assurance engineer. In 1997, he was awarded the PhD degree from the Australian National University for his dissertation on "Ion beam effects in GaAs-AlGaAs materials and devices". He has been the past recipient of the Australian Research Council Postdoctoral, QEII and Future Fellowships. He has published/co-published over 350 journal papers, including four book chapters. He is also a co-inventor in 4 US patents related to laser diodes and infrared photodetectors. His research interests include epitaxial growth of low-dimensional compound semiconductors, nanostructured optoelectronic devices and ion-implantation processing of compound semiconductors for optoelectronic device applications. Prof. Tan is a Senior Member of the IEEE.
