제목 Preparation and characterization of a new solid electrolyte, LiSiON, deposited by RF sputtering
초록 In thin study, we prepared and characterized LiSiON solid electrolyte by RF(radio frequency) sputtering. The surface morphologies and cross sectional view of thin films were characterized by FE-SEM(field-emission scanning electron microscopy).  Compositions of thin films were characterized by XPS(X-ray photoelectron spectroscopy). Ionic conductivity of thin-film electrolyte was measured in Cu/electrolyte/Cu sandwich structures on sapphire substrate with overlap area of 0.16 cm2 by EIS(electrochemical impedance spectroscopy). Cu used as blocking electrode with thickness of 100nm was deposited by DC magnetron sputtering in Ar atmosphere and LiSiON as solid electrolyte with thickness of 1um was deposited by RF sputtering in Ar and N2 atmosphere. EIS was performed in frequency range from 0.1Hz to 1MHz, using 10mV ac signal at room temperatures. Ionic conductivity of LiSiON was 10-6 S/cm, which is similar to those of other oxide electrolytes. Therefore, LiSiON can be a promising electrolyte in all-solid-state thin film batteries.
