Journal ArticleDOI
Reconfigurable Complementary Logic Circuits with Ambipolar Organic Transistors.
Hocheon Yoo,Matteo Ghittorelli,Edsger C. P. Smits,Gerwin H. Gelinck,Han-Koo Lee,Fabrizio Torricelli,Jae-Joon Kim +6 more
TL;DR: High-performance non-planar ambipolar organic transistors with electrical control of the polarity and orders of magnitude higher performances with respect to state-of-art split-gate ambipolar transistors are shown.
Journal ArticleDOI
Negative Transconductance Heterojunction Organic Transistors and their Application to Full-Swing Ternary Circuits.
TL;DR: The transient operation of a ternary inverter circuit is demonstrated for the first time and the proposed transistors and inverters exhibit hysteresis-free operation due to the use of a hydrophobic gate dielectric and encapsulating layers.
Journal ArticleDOI
Sensory Adaptation and Neuromorphic Phototransistors Based on CsPb(Br1-xIx)3 Perovskite and MoS2 Hybrid Structure.
Seongin Hong,Seung Hee Choi,Jongsun Park,Hocheon Yoo,Joo Youn Oh,Joo Youn Oh,Euyheon Hwang,Dae Ho Yoon,Sunkook Kim +8 more
TL;DR: Novel neuromorphic phototransistors that emulate human sensory adaptation in response to a continuous light stimulus, similar to the neural system are introduced using the light-induced halide phase segregation of CsPb(Br1-xIx)3 perovskite.
Journal ArticleDOI
Highly sensitive active pixel image sensor array driven by large-area bilayer MoS2 transistor circuitry
Seongin Hong,Nicolo Zagni,Sooho Choo,Na Liu,Seungho Baek,Arindam Bala,Hocheon Yoo,Byung Ha Kang,Hyun Jae Kim,Hyung-Joong Yun,Muhammad A. Alam,Sunkook Kim +11 more
TL;DR: In this article, a bilayer MoS2 phototransistor was used to synthesize an active pixel image sensor array for image sensing applications, which is composed of two-dimensional transition metal dichalcogenides (MoS2).
Journal ArticleDOI
Wafer-Scale and Low-Temperature Growth of 1T-WS2 Film for Efficient and Stable Hydrogen Evolution Reaction
Hyeong-U Kim,Hyeong-U Kim,Vinit Kanade,Mansu Kim,Ki Seok Kim,Byeong-Seon An,Hyunho Seok,Hocheon Yoo,Hocheon Yoo,Lindsay E. Chaney,Seung‐Il Kim,Cheol-Woong Yang,Geun Yong Yeom,Dongmok Whang,Jae-Hyun Lee,Taesung Kim +15 more
TL;DR: A uniform wafer-scale 1T-WS2 film is prepared using a plasma-enhanced chemical vapor deposition (PE-CVD) system and demonstrates its similar catalytic activity and high durability as compared to those of previously reported untreated and planar 1T -WS2 films synthesized with CVD and hydrothermal methods.
