Korean J. Met. Mater. 2023;61(7):509-513.   Published online 2023 Jun 21
DOI: https://doi.org/10.3365/KJMM.2023.61.7.509

Abstract
MgO nanowires were grown by a thermal evaporation method at different N2/O2 gas ratios in order to investigate the effect of oxygen concentration on the growth and luminescence properties of the MgO nanowires. A thermal evaporation process was conducted at 1000oC and under a pressure of 500Torr. No nanowires were..... More

Korean J. Met. Mater. 2023;61(6):444-448.   Published online 2023 May 18
DOI: https://doi.org/10.3365/KJMM.2023.61.6.444

Abstract
MgO nanowires with a branched structure were fabricated using a thermal evaporation method in air at atmospheric pressure. The branched MgO nanowire was made up of two parts: a primary central nanowire trunk and lots of secondary nanowire branches. The branched MgO nanowires had a 4-fold symmetrical structure. The secondary..... More

Korean J. Met. Mater. 2019;57(11):732-740.   Published online 2019 Nov 5
DOI: https://doi.org/10.3365/KJMM.2019.57.11.732

Abstract
To attain high life standards, it is important to develop high-performance non-toxic gas sensors for public safety, environmental pollutant control, industrial processes, etc. Because reports on single element semiconductor-coated semiconducting metal oxides for sensing applications are rare, we synthesized SnO2 nanowires and coated them with a 5 nm-thick or 10.....

Abstract
Silver nanowire (AgNWs) networks offer a promising approach for producing cost effective transparent electrode materials. However, high temperature annealing is necessary to achieve low sheet resistance, which limits the use of AgNWs for low temperature processing applications such as flexible electronics, and perovskites solar cell fabrication. This study shows that..... More
