Journal ArticleDOI
Effect of water in ambient air on hysteresis in pentacene field-effect transistors containing gate dielectrics coated with polymers with different functional groups
Se Hyun Kim,Hoichang Yang,Sang Yoon Yang,Kipyo Hong,Danbi Choi,Chanwoo Yang,Dae Sung Chung,Chan Eon Park +7 more
TL;DR: In this article, the effect of water in ambient air on the hysteresis phenomena of pentacene field effect transistors with polymer/SiO2 gate dielectrics was investigated.
Journal ArticleDOI
Reducing the contact resistance in organic thin-film transistors by introducing a PEDOT:PSS hole-injection layer
TL;DR: In this paper, gold electrodes were coated with poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) in order to reduce the contact resistance in pentacene organic field-effect transistors (OFETs).
Journal ArticleDOI
High-performance triisopropylsilylethynyl pentacene transistors via spin coating with a crystallization-assisting layer.
TL;DR: TIPS-PEN OFETs fabricated at a spin speed of 300 rpm with a CYTOP-patterned substrate showed a field-effect mobility of 0.131 cm(2) V(-1) s(-1), which is a remarkable improvement over previous spin-coated TIPS- PEN OfETs.
Journal ArticleDOI
High-performance solution-processed triisopropylsilylethynyl pentacene transistors and inverters fabricated by using the selective self-organization technique
Se Hyun Kim,Danbi Choi,Dae Sung Chung,Chanwoo Yang,Jaeyoung Jang,Chan Eon Park,Sang-Hee Ko Park +6 more
TL;DR: In this paper, a triisopropylsilylethynyl pentacene (TIPS-PEN) semiconductor was used to obtain selectively self-organized active layers of organic field effect transistors and inverters.
Journal ArticleDOI
Direct Observation of Interfacial Morphology in Poly(3-hexylthiophene) Transistors: Relationship between Grain Boundary and Field-Effect Mobility
Danbi Choi,Sangwoo Jin,Youngmin Lee,Se Hyun Kim,Dae Sung Chung,Kipyo Hong,Chanwoo Yang,Jungwoon Jung,Jin Kon Kim,Moonhor Ree,Chan Eon Park +10 more
TL;DR: In this paper, the effects of microstructural and morphological alternation on field effect mobility of poly(3-hexylthiophene) (P3HT) films were investigated.
