Ji Hun Um, Byoung Su Choi, Woo Sik Jang, Sungu Hwang, Dae-Woo Jeon, Jin Kon Kim, Hyun Cho
Korean J. Met. Mater. ;59(2):121-126.   Published online 2021 Jan 27
DOI: https://doi.org/10.3365/KJMM.2021.59.2.121

Abstract
α-Ga2O3 has the largest bandgap (~5.3 eV) among the five polymorphs of Ga2O3 and is a promising candidate for high power electronic and optoelectronic devices. To fabricate various device structures, it is important to establish an effective dry etch process which can provide practical etch rate, smooth surface morphology and..... More

DOI: https://doi.org/10.3365/KJMM.2017.55.4.290

Abstract
In this study, a glass fiber is fabricated using a continuous spinning process from alkali resistant (AR) glass with 4 wt% zirconia. In order to confirm the melting properties of the marble glass, the raw material is placed into a Pt crucible and melted at 1650 ℃ for 2 h,..... More
