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

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

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

Thermoelectric Transport Properties of Interface-Controlled <i>n</i>-type Bismuth Telluride Selenide Composites by Reduced Graphene Oxide

Korean J. Met. Mater. 2019;57(9):603-608.   Published online 2019 Aug 21
DOI: https://doi.org/10.3365/KJMM.2019.57.9.603

We report the effect of interface control using reduced graphene oxide (RGO) on the thermoelectric transport properties of Bi2Te2.7Se0.3 (BTS)-RGO composites. The interface-controlled BTS-RGO composites were prepared by the consolidation of BTS-RGO hybrid powders using spark plasma sintering (SPS). The RGO-hybridization reduced the grain size in the BTS-RGO composites because..... More

Korean J. Met. Mater. 2018;56(2):163-169.   Published online 2018 Feb 5
DOI: https://doi.org/10.3365/KJMM.2018.56.2.163

We report the effects of interface control using reduced graphene oxide (RGO) on the thermoelectric transport properties of polycrystalline SnSe compounds. Polycrystalline SnSe-RGO composites were prepared by the consolidation of SnSe powder coated with the RGO by hot pressing, and the RGO content was controlled to be 0, 0.2, 0.5..... More

Effect of E-Beams Irradiation Dose on the Sensing Properties of Pt-Functionalized Reduced Graphene Oxides Following Annealing of the 6 nm-Thick Pt Layer

Korean J. Met. Mater. 2017;55(7):492-502.   Published online 2017 Jul 4
DOI: https://doi.org/10.3365/KJMM.2017.55.7.492

Pt-functionalized RGO samples were prepared and subsequently irradiated with 2-MeV electron beams (e-beams). The effect of e-beam dose on the structural, electrical, and gas sensing properties of the samples was investigated. E-beam irradiation was found to induce significant microstructural changes in the Pt-functionalized RGO. Measurements of NO2 sensing at room..... More
