~ 2019学年度光电所所学会会长自我介绍 ~

「醒时同交欢,醉后各分散。永结无情游,相期邈云汉。」

光电所的师长、所办同仁以及同学们大家好,第19届2019学年度所学会会长夏尊尧,感恩欢欣在此报到,且荣幸开心地向各位报告。首先要先谢谢指导教授彭隆瀚老师的包容支持与鼓励,给予身心灵的启迪与升华。感谢黄建璋所长热诚相挺!感谢铁电材料光电组件实验室学弟妹们的相知相惜与协助。此外,亦深深感谢吴志毅老师实验室黄郁庭、蔡瑞祥、郭胜文三任会长的经验传承。

会长的工作任务,包含上学期的餐会、下学期的球类竞赛以及暑期的大学生光电营,希望为光电所同学在充实愉悦的研究生活中,增添璀璨青春元素之光采回忆。尊尧曾经在中央研究院物理所晶体实验室十年研究,深切明白实验室生活之酸甜苦辣,无论是捶胸顿足、懊恼沮丧,或是雀跃欢喜、荣耀成就。一周连续熬夜赶实验都乃家常便饭,午夜时分的中研院星空陪伴,更是充分满足了我傲狂科学的年轻岁月。因此,透过一些简单的活动,希望提供同学们交流请益、社交抒发的机会。也期盼同学们热烈参加,享受师长们美意提供的活动盛宴。

除此之外,要报告的是尊尧曾担任少尉值星官及炮兵前进观测官,要带领百人刺青部队操训演习,更曾行军经月,冲锋陷阵强攻山头,生活的感受和生命的历练够刺激完整。电子所毕业后,尊尧首选成为竹科工程师,弃各上市柜公司机会,千挑百选史丹佛电机博士直属长官,跟随学习世界一流的逻辑思考及放眼国际的研发制造。后续进入内科上市公司,引领团队从事计算机周边产品的生产销售。也曾于苏州工业园区,项目研发制造蓝宝石晶体基板。

向同学们报告这么多,主要是想透露尊尧学经历丰富,感恩承接机会筹组台大光电所所学会菁英团队,愿提供最自由自主之平台,发挥想象力及领导能力的创意空间,给您亦给我千载难逢的最佳机会,组成台大光电梦幻团队!明后年当各位昂然专精地步出校园,各公司都会很快将领导任务传承交付给您们,要迅速上手带领团队,需要伤脑筋、动智慧,激励成员达成各项目任务。所以,竭诚欢迎各位,百忙之中给自己一个挑战、给大家一个机会,让我们一起青春不留白,让我们一起共事,为光电所最优秀的师长同学们服务,这是我们的荣耀!

衷心祝福各位光电所同学们学习研究顺心如意,学有所成欢欣毕业。无论在竹科、内科、中科、南科,在软件园区,甚至在中国大陆或是在欧美各产业处,都能开心欢喜发光发电,开创、拥有及享受美丽光电人生。

 
 
 
     

~ The 4th International Conference on BioPhotonics; ICB 2019

(September 15~18, 2019, at Barry Lam Hall, NTU)

The 4th International Conference on BioPhotonics (ICB; http://icb2019.ntu.edu.tw/) was held at the Barry Lam Hall of the National Taiwan University during Sept. 15–18, 2019. More than 150 scholars and graduate students were registered from more than 10 countries. The goal of the ICB is to have technical exchanges and networking among the leading academics worldwide. Emergent areas that have the potential to significantly benefit our future life, such as precision medicine, cell/immune-therapy, liquid biopsy, optical biopsy, artificial intelligence on biomedicine, were addressed in the 42 papers during the ICB 2019.

Many renowned speakers shared their latest achievements and insights on the future of research in biophotonics ranging from life science to clinical applications. Professor Xingde Li, Johns Hopkins University, U.S.A. addressed OCT and endomicroscopy towards visualization of histology; Prof. Marcus Sauer, University of Wuerzburg, Germany addressed single-molecule sensitive super-resolution microscopy, and Prof. Ann-Shyn Chiang, National Tsing Hua University addressed mapping the Drosophila engram.

This year, we had a teleconference session, which was delivered by Prof. Roel Baets of the Ghent University, Belgium. He delivered the talk while he was in Washington DC, US. It was a good experience to witness the power of photonics technology by reducing the physical transportation in response to global warming.

The ICB 2019 was jointly sponsored by the National Taiwan University, the Taipei and Italy Chapters of IEEE Photonics Society, IEEE Engineering in Medicine and Biology Society, and Taiwan Photonics Society. The Organizers also appreciate the funding support by the Ministry of Science and Technology, Taiwan as well as the industrial sponsorships from Apollo Medical Optics and Crystalvue Medical Corporation.

Development of Anti-UV Structures for OLED Displays

Professor Chung-Chih Wu

Graduate Institute of Photonics and Optoelectronics, National Taiwan University

台湾大学光电所 吴忠帜教授

Although OLED displays are penetrating into wider applications in consumer electronics due to their high efficiency, high contrast, and good color gamut etc., their extension to outdoor applications (e.g., wearable, vehicular, signage applications etc.) is still facing significant reliability challenges. One major issue is their weak resistance against the UV-light induced degradation; the ultraviolet light (UV-light, λ<400nm) and high energy visible light (HEV-light, 400 < λ < 450 nm) in sunlight would significantly degrade OLEDs and much shorten display lifetimes. Thus, an effective anti-UV technique, that can protect OLEDs from UV/HEV damage and meanwhile maintain display performance, is strongly required. Here we report the development of effective anti-UV/HEV, high-transmittance, high-image-quality structures for OLED display panels based on carefully designed optical thin-film structures composed of more robust inorganic UV-absorbing and dielectric materials, instead of polymer/organic materials that may suffer yellowing by UV radiation.

论文题目:第一原理新颖信道与铁电材料研究及后端依时性介电崩溃之可靠度模型

姓名:陈品翔   指导教授:刘致为教授

 

摘要

当晶体管尺寸持续微缩后,使用具有高迁移率的信道材料来增加驱动电流或降低能耗是未来半导体组件发展的方向之一。在论文的第一部分将会针对锗之同素异形体,蓝丝黛尔锗(lonsdaleite Ge)进行特性分析,包含其能带结构、等效质量、弹道电流以及应变响应等皆会详细分析。具有稳定结构之蓝丝黛尔锗预期能有效提升组件表现而不改变其材料构成,而其直接能隙之特性亦利于用于光电组件之应用。

组件在设计上,其截止电流须保持相同或者更低以保持低静态功率,与此同时,亦须保持高的操作电流,因此,尽可能降低组件之次臨界摆幅十分重要。加入铁电材料到闸极堆栈的负电容场效应晶体管,其利用铁电材料内之偶极矩随偏压改变时改变极化方向之特性,将能使次臨界摆幅有效克服传统织极限值。在论文的第二部分,将以第一原理进行正交结构氧化锆铪(HfZrO2)之特性分析,利用其能量与极化之关系确定其铁电特性。以及,利用分子动力学模型计算其动态反应。除此之外,亦会探讨应变对其造成之影响。

在组件尺寸不断微缩的过程中,其失效机制亦是十分重要的一环,故在此论文中亦会探讨后段制程(BEOL)中介电层的崩溃机制,造成介电层崩溃的原因可能为施加电场或是漏电流造成,如何精确的了解其机制并藉此预测其可靠度变化是十分重要的。藉由后段制程中介电层之漏电流以及时依性介电层崩溃之数据,建立可靠度的模型,藉以进行组件于正常使用状态下之可靠度预测。
