Journal ArticleDOI
Structural inversion in 3-D hexagonal organization of coil-rod-coil molecule.
TL;DR: This work reports an unusual example of supramolecular structural inversion in coil-rod-coil molecules, from organized coil perforations in a rod layers to organized discrete rod-bundles in a coil matrix, while maintaining a 3-D hexagonal superlattice.
Journal ArticleDOI
Transient SHG Imaging on Ultrafast Carrier Dynamics of MoS2 Nanosheets
Houk Jang,Krishna P. Dhakal,Kyung Il Joo,Won Seok Yun,Sachin M. Shinde,Xiang Chen,Soon Moon Jeong,Suk Woo Lee,Zonghoon Lee,Jae Dong Lee,Jong Hyun Ahn,Hyunmin Kim +11 more
TL;DR: The generation of exciton-coupled phonon vibration from molybdenum disulfide nanosheets in a pre-excitonic resonance condition is reported and TSHG microscopy reveals critical information about the phase and amplitude of the acoustic phonons from different edge chiralities of the MoS2 monolayers.
Journal ArticleDOI
Probing the upper band gap of atomic rhenium disulfide layers
TL;DR: Observing the ultrafast intra-conduction band transitions, the researchers confirmed the existence of the high-energy band gap in bilayers of ReS2, leading to their potential for use in a range of optoelectronic applications, including solar cells and light emitting diodes.
Journal ArticleDOI
Synthesis of two-dimensional MoS2/graphene heterostructure by atomic layer deposition using MoF6 precursor
Youngjun Kim,Daeguen Choi,Whang Je Woo,Jae Bok Lee,Gyeong Hee Ryu,Jun Hyung Lim,Sunhee Lee,Zonghoon Lee,Seongil Im,Jong Hyun Ahn,Woo Hee Kim,Jusang Park,Hyungjun Kim +12 more
TL;DR: In this article, a halide precursor was used for the synthesis of 2D transition metal dichalcogenide (TMD) heterostructures using atomic layer deposition (ALD).
Journal ArticleDOI
Biologically Plausible Artificial Synaptic Array: Replicating Ebbinghaus' Memory Curve with Selective Attention.
Dong Gue Roe,Seongchan Kim,Yoon Young Choi,Hwije Woo,Moon Sung Kang,Young Jae Song,Jong Hyun Ahn,Yoonmyung Lee,Jeong Ho Cho +8 more
TL;DR: Inspired by the memorization process of the human brain, an artificial synaptic array is presented in this article, which mimics the biological memorisation process by replicating Ebbinghaus' forgetting curve.
