About the Workshop

Asia-Pacific Workshop on Widegap Semiconductors 2022 (APWS2022) will be held at the COZZI Blu, Taoyuan, Taiwan, November 13-18, 2022. The 10th  APWS (2022) follows a series of successful meetings last held in Awajishima, Japan (APWS2003), Hsinchu, Taiwan (APWS2005), Jeonju, Korea (APWS2007), Zhangjiajie, China (APWS2009), Toba, Japan (APWS2011), New Taipei, Taiwan (APWS2013), Seoul, Korea (APWS2015), Qingdao, China (APWS2017), and Okinawa, Japan (APWS 2019). The workshop presents high-level scientific and technological advances in materials and devices based on wide bandgap semiconductors and featured plenary sessions, parallel topical sessions, poster sessions and an industrial exhibition.

Workshop Topics

APWS2022 workshop will highlight latest advances in the field of wide bandgap materials including III-nitrides, silicon carbide, oxides, and diamond, and devices. Topical symposia will cover growth, characterization, optical and electronic devices.

Crystal Growth

Bulk growth, epitaxial growth, doping and point defects, growth methods, and related technology


Optical and electrical properties, structural analysis, and theory and simulation


Visible, UV, and white LEDs, micro LEDs, laser diodes, solar cells, detectors, transistors, diodes, high-power and high-frequency devices, device processing, contacts, and reliability.

System applications of wide bandgap semiconductors

About Taoyuan

APWS2022 will be held in Taoyuan, the city lying in northwestern Taiwan. Taoyuan is home to the largest and busiest airport on the island, Taoyuan International Airport (TPE), which listed as the 11th busiest airport worldwide by international passenger traffic. Serving as the main international entrance to Taiwan, Taoyuan is also known as the “Land of a Thousand Ponds”. The ponds and pools, scattering across the city, played important roles in irrigation and water storage in old days. Though losing the important functions nowadays, these ponds are regaining their values in tourism, culture and ecology. Over the years, Taoyuan has developed many distinctive attractions, including the Chiang Kai-Shek and Chiang Ching-Kuo Cultural Park (Cihu), Lala Mountain, Shihmen Reservoir, etc. These popular sites attract millions of visitors every year.
