조승근, 문해인, 김영원, 도환수, 이정우
Korean J. Met. Mater. 2022;60(8):570-576.   Published online 2022 Jul 12
DOI: https://doi.org/10.3365/KJMM.2022.60.8.570

Abstract
Transparent heaters are promising devices because of their versatile applications in vehicles, smart windows, and sensors, etc. Indium tin oxide is widely used for transparent heater materials due to its high electronic conductivity and visible light transmittance. However, the cost of indium is too high, and its fabrication needs sophisticated..... More

Fabrication of Mesh-Patterned Transparent Heater using Large-Sized Sheets of Reduced Graphene Oxide
대면적 시트의 환원된 산화 그래핀을 활용한 메쉬 패턴 투명히터 제작
Hae-In Moon, Seung Geun Jo, Yujin Shin, Yeoul Kang, Jung Woo Lee
문해인, 조승근, 신유진, 강여울, 이정우
Korean J. Met. Mater. 2022;60(8):564-569.   Published online 2022 Jul 12
DOI: https://doi.org/10.3365/KJMM.2022.60.8.564

Abstract
Transparent heaters are widely used for defrosting to improve visibility, insulation or heating of buildings, and thermal treatment. Indium tin oxide (ITO), which has excellent transmittance and electrical conductivity, is one of the representative materials used for these transparent heaters. However, it has several drawbacks including high material price, limited..... More

Korean J. Met. Mater. 2022;60(7):511-516.   Published online 2022 Jun 3
DOI: https://doi.org/10.3365/KJMM.2022.60.7.511

Abstract
In this study, ultrathin (4-40 nm) Cu-layer-based transparent heaters prepared on glass substrates were investigated for cost-effective applications. The Cu heaters were embedded between ZnO layers serving as anti-reflection and anti-corrosion layers. The Cu layer thicknesses varied in the range of 4-40 nm, and the corresponding structural, electrical, optical and..... More

                
Fabrication of Semi-transparent W film Heaters via Phase Transformation
텅스텐 나노박막의 상변태를 이용한 반투명 면상발열체 형성 연구
Jiyun Choi, Dooho Choi
최지윤, 최두호
Korean J. Met. Mater. 2021;59(9):664-669.   Published online 2021 Aug 4
DOI: https://doi.org/10.3365/KJMM.2021.59.9.664

Abstract
In this study, we prepared highly thermostable semi-transparent heaters composed of W layers with thicknesses of 1-20 nm, on which a 30 nm-thick ZnO layer was deposited to serve as an anti-oxidation barrier. The optical transmittance and sheet resistance of the heaters could be greatly modulated by varying the W..... More

방금혁, 최두호
Korean J. Met. Mater. 2021;59(3):155-161.   Published online 2021 Feb 19
DOI: https://doi.org/10.3365/KJMM.2021.59.3.155

Abstract
In this study, we report a methodology that simultaneously improved the corrosion resistance and visible transparency of ZnO/Cu/ZnO transparent heaters with the addition of reactively sputtered Al2O3 layers. To assess corrosion resistance, ZnO and Al2O3 layers with thicknesses in the range of 0-20 nm were deposited onto 20 nm-thick Cu..... More
