Structurally engineered colloidal quantum dot phosphor using TiO2 photonic crystal backbone
Autor: Hansol Lee, Tae-Yun Lee, Yeonsang Park, Kyung-Sang Cho, Young-Geun Rho, Hyuck Choo, Heonsu Jeon
Publikováno v: Light: Science & Applications, Vol 11, Iss 1, Pp 1-8 (2022)
Two-dimensional photonic crystal phosphor is upgraded in terms of both material and structure, which results in ~7 times enhanced color conversion efficiency compared with reference phosphor.

Color-selective photodetection from intermediate colloidal quantum dots buried in amorphous-oxide semiconductors
Autor: Kyung-Sang Cho, Keun Heo, Chan-Wook Baik, Jun Young Choi, Heejeong Jeong, Sungwoo Hwang, Sang Yeol Lee
Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-9 (2017)
The development of highly sensitive photodetectors is important for image sensing and optical communication applications. Cho et al., report ultra-sensitive photodetectors based on monolayered quantum dots buried in between amorphous-oxide semiconduc

Electrical Performance of Amorphous Oxide/Colloidal Quantum Dot/Amorphous Oxide Hybrid Thin Film Transistor
Autor: Kyung Sang Cho, Byeong Hyeon Lee, Sang Yeol Lee, Sangsig Kim
Publikováno v: Transactions on Electrical and Electronic Materials. 23:25-29
Hybrid-type thin-film transistors were fabricated using amorphous oxide and colloidal quantum dots. To prevent damage to the quantum dots, amorphous SIZO, which can be processed at low temperatures, was deposited by RF sputtering. In the case of a ge
