Journal ArticleDOI
Selective-area fluorination of graphene with fluoropolymer and laser irradiation
Wi Hyoung Lee,Ji Won Suk,Harry Chou,Jongho Lee,Yufeng Hao,Yaping Wu,Richard D. Piner,Deji Akinwande,Kwang S. Kim,Rodney S. Ruoff +9 more
TL;DR: A method to selectively fluorinate graphene by irradiating fluoropolymer-covered graphene with a laser, which leads to a dramatic increase in the resistance of the graphene while the basic skeletal structure of the carbon bonding network is maintained.
Journal ArticleDOI
Highly selective CO2 capture by S-doped microporous carbon materials
Humaira Seema,K. Christian Kemp,Nhien H. Le,Sung-Woo Park,Vimlesh Chandra,Jung Woo Lee,Kwang S. Kim +6 more
TL;DR: S-doped microporous carbon materials were synthesized by the chemical activation of a reduced-graphene-oxide/poly-thiophene material as discussed by the authors, which showed a large CO 2 adsorption capacity of 4.5mmolg −1 at 298 K and 1m, as well as an impressive CO 2 selectivity over N 2, CH 4 and H 2.
Journal ArticleDOI
Single-Gate Bandgap Opening of Bilayer Graphene by Dual Molecular Doping
Jaesung Park,Sae Byeok Jo,Young-Jun Yu,Young-Jun Yu,Youngsoo Kim,Jae Won Yang,Wi Hyoung Lee,Hyun Ho Kim,Byung Hee Hong,Byung Hee Hong,Philip Kim,Kilwon Cho,Kwang S. Kim +12 more
TL;DR: This work unambiguously proves that it is possible to open a bandgap with two molecular dopants (F4-TCNQ and NH2 -functionalized self-assembled monolayers (SAMs) even in a single-gate device structure.
Journal ArticleDOI
Cation-π Interactions: A Theoretical Investigation of the Interaction of Metallic and Organic Cations with Alkenes, Arenes, and Heteroarenes
TL;DR: In this article, the authors examined the nature of the cation−π interaction by carrying out high level ab initio calculations of both metallic (Li+,Na+,K+, and Ag+) and organic (NH4+, C(NH2)3+, and N(CH3)4+) cations with different classes of π systems, viz alkenes (ethene), arenes (benzene), and heteroarenes (pyrrole).
Journal ArticleDOI
Comparative ab initio study of the structures, energetics and spectra of X−⋅(H2O)n=1–4 [X=F, Cl, Br, I] clusters
TL;DR: In this paper, the authors compared the structures of different halide water clusters and found that the predicted minimum energy geometries for different cluster are accompanied by several other structures close to these global minima.
