Influence of thickness of poly(3-hexylthiophene-2,5-diyl) hole transport layer on electrical characteristics of lead sulfide quantum dot-based shortwave infrared photodiodes

Autor: Sungkeun Baang, Jaehoon Park, Jin-Hyuk Bae, Kyeong-Ho Seo, Xue Zhang

Publikováno v: Journal of the Korean Physical Society. 79:512-520

Lead sulfide quantum dots (PbS QDs) have emerged as one of the promising photoactive materials for shortwave infrared (SWIR) photodiodes because of their uncooled processability, cost efficiency, and broadband tunability. In this study, PbS QD-based

Importance of Solvent Evaporation Temperature in Pre-Annealing Stage for Solution-Processed Zinc Tin Oxide Thin-Film Transistors

Autor: Sang-Hwa Jeon, Ziyuan Wang, Kyeong-Ho Seo, Junhao Feng, Xue Zhang, Jaehoon Park, Jin-Hyuk Bae

Publikováno v: Electronics; Volume 11; Issue 18; Pages: 2822

We focused on the importance of solvent evaporation governed by the temperature of the pre-annealing stage (TS) in solution-processed zinc tin oxide (ZTO) thin-film transistors (TFTs). We controlled TS based on the boiling point (BP) of the solvent u
