Research detail
This work presents a method to control oxygen vacancies in solution-processed amorphous InZnO films using argon plasma and annealing. The vacancies enhance conductivity and can be reversed by heat treatment. Using synchrotron analysis, the study links atomic-scale changes to device performance, offering a pathway for tuning electronic properties in next-generation flexible and transparent oxide electronics.
Comment
I am deeply honored to receive this recognition at EM-NANO 2025. This award is a meaningful acknowledgment of our efforts in advancing oxygen vacancy engineering in solution-processed oxide semiconductors. I would like to express my sincere gratitude to Assistant Professor Juan Paolo Bermundo, Professor Yukiharu Uraoka, and Associate Professor Ratchatee Techapiesancharoenkij for their invaluable guidance and support. I also extend my thanks to all members and staff of the Information Device Science Laboratory, as well as to the Synchrotron Light Research Institute in Thailand for enabling the advanced spectroscopic analysis. This recognition inspires me to continue contributing to the development of flexible and transparent electronics through materials innovation.
