果尚志主任個人簡介：
果尚志(Shangjr Gwo)， 1985年獲國立交通大學電子工程系學士學位，1993年獲美國德州大學奧斯汀分校物理博士學位。1994至1997年在日本筑波市JRCAT研究機構(日本通產省10年奈米科技研究計畫)及產業技術融合領域研究所任職研究員。1997年起進入國立清華大學物理系，擔任教職及研究工作，2010年起擔任物理系講座教授及奈微所合聘教授。自2014年8月1日起，果尚志教授被借調至財團法人國家同步輻射研究中心擔任主任。果尚志教授學術生涯的研究工作集中於低維次奈米材料(其中包括半導體、自組裝分子膜及貴金屬奈米粒子)的基本物理性質和元件應用、奈米電漿子光學(Nanoplasmonics)、三族氮化物半導體(III-Nitride Semiconductor)之電漿輔助式分子束磊晶成長(Molecular-Beam Epitaxy)以及利用同步輻射光源進行半導體表面及界面之基礎物性研究。

Civilization began when humans invented the fire-making technique about 300,000 years ago. For a long time, fire is a dependable source of light and warmth, as well as an enabling tool for cooking and socialization. It is no exaggeration to say that the use of fire as a lighting/heating source makes the first significant difference between humans and the other animals on Earth. The development of new light sources has accelerated in the past 120 years. Starting from the invention of X-ray tube by Wilhelm Röntgen in 1895, new light sources including synchrotron radiation source (1947), maser (1954), laser (1960), visible-light light-emitting diode (1962), and semiconductor diode laser (1962), have revolutionized our lives. In this talk, I will present some of the most recent developments in cutting-edge light sources with different sizes (ultrasmall and ultralarge), spectral regions (X-ray, ultraviolet, visible, infrared, terahertz), pulse widths (ultrafast), and power intensities (ultralow or ultrastrong). The prospective applications using these cutting-edge light sources will also be presented.
