Journal ArticleDOI
On the Current-Voltage Hysteresis in Perovskite Solar Cells: Dependence on Perovskite Composition and Methods to Remove Hysteresis
Dong-Ho Kang,Nam-Gyu Park +1 more
TL;DR: It is proposed from the current studies that engineering of perovskite film near the electron transporting layer and the hole transporting layer is of vital importance for achieving hysteresis-free PSCs and extremely high efficiency.
Journal ArticleDOI
Phosphorene/rhenium disulfide heterojunction-based negative differential resistance device for multi-valued logic.
Jaewoo Shim,Seyong Oh,Dong-Ho Kang,Seo-Hyeon Jo,Muhammad Hasnain Ali,Woo-Young Choi,Keun Heo,Jaeho Jeon,Sungjoo Lee,Minwoo Kim,Young Jae Song,Jin-Hong Park +11 more
TL;DR: This work demonstrates a negative differential resistance device based on a phosphorene/rhenium disulfide (BP/ReS2) heterojunction that is formed by type-III broken-gap band alignment, showing high peak-to-valley current ratio values and a ternary inverter as a multi-valued logic application.
Journal ArticleDOI
High-Performance Transition Metal Dichalcogenide Photodetectors Enhanced by Self-Assembled Monolayer Doping
Dong-Ho Kang,Myungsoo Kim,Jaewoo Shim,Jeaho Jeon,Hyung-Youl Park,Woo-Shik Jung,Hyun Yong Yu,Changhyun Pang,Sungjoo Lee,Jin-Hong Park +9 more
TL;DR: In this paper, the effect of self-assembled monolayer (SAM)-based doping on the performance of WSe2-and MoS2-based transistors and photodetectors is investigated.
Journal ArticleDOI
An Ultrahigh-Performance Photodetector based on a Perovskite-Transition-Metal-Dichalcogenide Hybrid Structure.
Dong-Ho Kang,Seong Ryul Pae,Jaewoo Shim,Gwangwe Yoo,Jaeho Jeon,Jung Woo Leem,Jae Su Yu,Sungjoo Lee,Byungha Shin,Jin-Hong Park +9 more
TL;DR: An ultrahigh performance MoS2 photodetector with high photoresponsivity, minimized down to 20% by adopting a new encapsulation bilayer of octadecyltrichlorosilane/polymethyl methacrylate.
Journal ArticleDOI
High-Performance 2D Rhenium Disulfide (ReS2) Transistors and Photodetectors by Oxygen Plasma Treatment
Jaewoo Shim,Aely Oh,Dong-Ho Kang,Seyong Oh,Sung Kyu Jang,Jaeho Jeon,Min Hwan Jeon,Minwoo Kim,Chang Hwan Choi,Jaehyeong Lee,Sungjoo Lee,Geun Young Yeom,Young Jae Song,Jin-Hong Park +13 more
TL;DR: A high-performance ReS2 -based thin-film transistor and photodetector with high on/off-current ratio, high mobility, and fast temporal response through O2 plasma treatment is reported.
