Ag 중간층이 SnO2 박막의 광학적, 전기적 특성에 미치는 영향

Abstract

SnO2 single layer and SnO2/Ag/SnO2 (SAS) tri-layered films were deposited on the glass substrate by RF and DC magnetron sputtering at room temperature and then the effect of Ag interlayer on the opto-electrical performance of the films were considered. As deposited SnO2 films show a visible transmittance of 85.5 % and a sheet resistance of 1.2?104 Ω/□, the SAS films with a 15 nm thick Ag interlayer show a lower resistance of 18.8 Ω/□ and a visible transmittance of 70.6 %, respectively. The figure of merit based on the optical transmittance and sheet resistance revealed that the Ag interlayer in the SnO2 films enhances the opto-electrical performance without substrate heating or annealing process.
