The 9th Asia-Pacific Workshop on Widegap Semiconductors (APWS2019)

About workshop

The 9th Asia-Pacific Workshop on Widegap Semiconductors (APWS2019) will be held in Onna-son, Okinawa, Japan from November 10 to 15, 2019. The previous eight workshops were held in Awajishima, Japan (APWS2003), Hsinchu, Taiwan (APWS2005), Jeonju, Korea (APWS2007), Zhangjiajie, China (APWS2009), Toba, Japan (APWS2011), New Taipei, Taiwan (APWS2013), Seoul, Korea (APWS2015), and Qingdao, China (APWS2017). Researchers from the Asia and Pacific region will join those from other parts of the world in stimulating discussions on widegap semiconductors.

Widegap semiconductors, including III-nitrides, silicon carbide, oxides, and diamond, have excellent physical properties. There are many obstacles on the road to high-performance optical and electronic devices, including difficulties in epitaxy and device processing. The objective of this workshop is to share high-level research results, spread the understanding of widegap semiconductors through in-depth discussions, and contribute to breakthroughs that can overcome critical technological barriers to improve the performance of widegap semiconductor devices.

Workshop topics

APWS2019 focuses on the science and technology of widegap semiconductors, including III-nitrides, silicon carbide, oxides, diamond and so forth. Research has led to developments in optical and electronic devices, including those for environmental and energy applications. The following topics will be discussed:

• Growth
