Journal ArticleDOI
High-mobility and low-power thin-film transistors based on multilayer MoS2 crystals
Sunkook Kim,Sunkook Kim,Aniruddha Konar,Wan Sik Hwang,Jong Hak Lee,Jiyoul Lee,Jaehyun Yang,Changhoon Jung,Hyoungsub Kim,Ji-Beom Yoo,Jae-Young Choi,Yong Wan Jin,Sang Yoon Lee,Debdeep Jena,Woong Choi,Woong Choi,Kinam Kim +16 more
TL;DR: This is the first comprehensive investigation of process-friendly multilayer molybdenum disulphide field-effect transistors and their results provide potentially important implications in the fabrication of high-resolution large-area displays and further scientific investigation of various physical properties expected in other layered semiconductors.
Journal ArticleDOI
High-detectivity multilayer MoS(2) phototransistors with spectral response from ultraviolet to infrared.
Woong Choi,Mi Yeon Cho,Aniruddha Konar,Jong Hak Lee,Gi Beom Cha,Soon Cheol Hong,Sangsig Kim,Jeongyong Kim,Debdeep Jena,Jinsoo Joo,Sunkook Kim +10 more
TL;DR: Multilayer MoS(2) phototransistors further exhibit high room temperature mobilities, near-ideal subthreshold swings, low operating gate biases, and negligible shifts in the threshold voltages during illumination.
Journal ArticleDOI
Low-Power Flexible Organic Light-Emitting Diode Display Device
Sunkook Kim,Hyuk-Jun Kwon,Sunghun Lee,Hong-shik Shim,Youngtea Chun,Woong Choi,Jin-ho Kwack,Dong-Won Han,Myoung-Seop Song,Sungchul Kim,Saeed Mohammadi,In-Seo Kee,Sang Yoon Lee +12 more
TL;DR: In order to achieve a highly fl exible OLED display device, the following characteristics are needed: i) a low temperature process to prevent deformation in plastic substrates, ii) a new optical architecture providing both fl exibility and high outdoor readability, iii) a thinner and lighter platform than for current OLED technologies that allows bending and folding.
Journal ArticleDOI
Enhanced Performance in Polymer Solar Cells by Surface Energy Control
Xavier Bulliard,Soo-Ghang Ihn,Sungyoung Yun,Yungi Kim,Dukhyun Choi,Joe Young Choi,Min Kim,Myungsun Sim,Jong Hwan Park,Woong Choi,Kilwon Cho +10 more
TL;DR: In this paper, the surface energy of a zinc oxide buffer layer is controlled to increase the power conversion efficiency of an inverted-type polymer solar cell by using a mixed self-assembled monolayer.
Journal ArticleDOI
Two-dimensional Layered MoS2 Biosensors Enable Highly Sensitive Detection of Biomolecules
Joonhyung Lee,Piyush Dak,Yeonsung Lee,Heekyeong Park,Woong Choi,Muhammad A. Alam,Sunkook Kim +6 more
TL;DR: The experimental demonstration and the theoretical framework provide a comprehensive description of the performance potential of dielectric-free MoS2-based biosensor technology.
