Korean J. Met. Mater. 2019;57(12):795-800.   Published online 2019 Nov 22
DOI: https://doi.org/10.3365/KJMM.2019.57.12.795

Abstract
With the expanding development of flexible optoelectronic devices, the need for high-performance (i.e., high conductivity, high transmittance and flexibility) transparent conductive electrodes has grown. In this study, the critical role of thickness for each of the layers in ZnO/Cu/ZnO transparent conductive electrodes (TCE) for optoelectronic devices has been investigated. The.....

91 Optimization of ZnO/Ag/ZnO Transparent Conductive Electrodes Fabricated by Magnetron Sputtering
스퍼터링법으로 증착된 ZnO/Ag/ZnO 투명전극의 성능 최적화 연구
Woo Hyeon Jo, Dooho Choi
조우현, 최두호
Korean J. Met. Mater. 2019;57(2):91-96.   Published online 2019 Jan 11
DOI: https://doi.org/10.3365/KJMM.2019.57.2.91

Abstract
The critical role of the thicknesses of the top and bottom oxide layers, as well as Ag layer, in ZnO/Ag/ZnO transparent conductive electrodes were investigated. The Ag forms a nearly continuous layer at the thickness of 8 nm, at which the Ag sheet resistance of 8.0 Ω/Sq. is lower than..... More

Korean J. Met. Mater. 2018;56(8):605-610.   Published online 2018 Aug 5
DOI: https://doi.org/10.3365/KJMM.2018.56.8.605

Abstract
Severe resistivity size effect in Cu interconnects is attributed to the relatively long bulk electron mean free path (39 nm at 298 K), which is inherently determined by phonon scattering. In this regard, Ru and Co have been recently considered as attractive alternatives for next-generation interconnect materials because the significantly..... More
