Recovery Improvement for Large-Area Tungsten Diselenide Gas Sensors
Kyung Yong Ko,Kyunam Park,Sangyoon Lee,Youngjun Kim,Whang Je Woo,Dong-Hyun Kim,Jeong Gyu Song,Jusang Park,Hyungjun Kim +8 more
TL;DR: Improved recovery of the WSe2 gas sensor's NO2-sensing performance by utilizing external thermal energy is demonstrated by reacting NH3 and adsorbed NO2 on the surface of WSe1 and the recovery time is dramatically decreased.
Journal ArticleDOI

Journal ArticleDOI
High-Performance Gas Sensor Using a Large-Area WS2 xSe2-2 x Alloy for Low-Power Operation Wearable Applications.
Kyung Yong Ko,Sangyoon Lee,Kyunam Park,Youngjun Kim,Whang Je Woo,Dong-Hyun Kim,Jeong Gyu Song,Jusang Park,Jung Hwa Kim,Zonghoon Lee,Hyungjun Kim +10 more
TL;DR: The results show that the proposed method is a promising strategy to improve 2D TMDC gas sensors and has a potential for applications in advanced gas-sensing devices.
Journal ArticleDOI
Poisson–Gaussian Noise Analysis and Estimation for Low-Dose X-ray Images in the NSCT Domain
TL;DR: In this article, the authors used artificially generated noise to analyze and estimate the Poisson-Gaussian noise of low-dose X-ray images in the NSCT domain, and the noise distribution of the subband coefficients was analyzed using the noiseless low-band coefficients and the variance of the noisy subbands coefficients.
Journal ArticleDOI
Atomic-Layer-Deposition-Based 2D Transition Metal Chalcogenides: Synthesis, Modulation, and Applications.
Youngjun Kim,Whang Je Woo,Dong-Hyun Kim,Sangyoon Lee,Seung-Min Chung,Jusang Park,Hyungjun Kim +6 more
TL;DR: In this article, the synthesis and modulation of transition metal chalcogenides (TMCs) by ALD is described, and the characteristics of ALD-based TMCs used in nanoelectronics, sensors, and energy applications are discussed.
