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
One-Step Exfoliation Synthesis of Easily Soluble Graphite and Transparent Conducting Graphene Sheets
Jong Hak Lee,Dong-Wook Shin,Victor G. Makotchenko,A. S. Nazarov,Vladimir E. Fedorov,Yu Hee Kim,Jae-Young Choi,Jong Min Kim,Ji-Beom Yoo +8 more
TL;DR: Easily soluble expanded graphite is synthesized in a one-step exfoliation process that can be used for the lowcost mass production of graphene for various applications because of the simplicity and speed of the process.
Journal ArticleDOI
Giant spin Hall effect in graphene grown by chemical vapour deposition.
Jayakumar Balakrishnan,Jayakumar Balakrishnan,Gavin Kok Wai Koon,Ahmet Avsar,Yuda Ho,Jong Hak Lee,Manu Jaiswal,Manu Jaiswal,Seung Jae Baeck,Jong Hyun Ahn,Aires Ferreira,Aires Ferreira,Miguel A. Cazalilla,Miguel A. Cazalilla,Antonio H. Castro Neto,Barbaros Özyilmaz +15 more
TL;DR: It is shown that graphene grown by chemical vapour deposition on copper is equally promising for spintronics applications, and chemically synthesized graphene has a strong spin-orbit coupling as high as 20 meV giving rise to a giant spin Hall effect.
Journal ArticleDOI
A role of HNO3 on transparent conducting film with single-walled carbon nanotubes
TL;DR: The results suggest that p-type doping has a larger effect on the sheet resistance than the removal of residual N-methylpyrrolidone by an HNO3 treatment.
Journal ArticleDOI
Synthesis of shape-controlled β-In2S3 nanotubes through oriented attachment of nanoparticles
TL;DR: The beta-In(2)S(3) nanotubes had a diameter, wall thickness and length of 5.0 nm, 0.79 nm and >10 microm, respectively.
