Ho Kun Woo,Min Su Kang,Taesung Park,Junsung Bang,Sanghyun Jeon,Woo Seok Lee,Junhyuk Ahn,Geonhee Cho,Dong Kyun Ko,Younghoon Kim,Don-Hyung Ha,Soong Ju Oh +11 more
TL;DR: Electrical, structural, and optical analyses demonstrated that the colloidal-annealing of ZnO NPs effectively passivated the defects and simultaneously shifted their band diagram; therefore, colloidal -annealing is a more favorable method as compared to conventional film-annealed.
Journal ArticleDOI
Controllable doping and passivation of ZnO thin films by surface chemistry modification to design low-cost and high-performance thin film transistors
TL;DR: A surface passivation process involving treatment with 3-aminopropyltriethoxysilane (APTES) that can enhance the electrical properties of ZnO sol-gel thin films was introduced in this paper.
Journal ArticleDOI
Designing High-Performance CdSe Nanocrystal Thin-Film Transistors Based on Solution Process of Simultaneous Ligand Exchange, Trap Passivation, and Doping
Woo Seok Lee,Yoon-Gu Kang,Ho Kun Woo,Junhyuk Ahn,Haneun Kim,Donggyu Kim,Sanghyun Jeon,Myung Joon Han,Ji Hyuk Choi,Soong Ju Oh +9 more
TL;DR: In this paper, a simple solution-based and postsynthetic process for simultaneous ligand exchange, surface passivation, and doping of CdSe nanocrystals (NCs) for the design of high-performance field-engineered field-effectors is described.
