Development of Transparent LSCO and LSCNO Conductors for Optical Shutter Systems
Abstract
We have prepared lanthanum strontium cobalt oxide La(0.50)50Sr(0.50)Co(0.50)Ni(0.50)O3; LSCNO 50/50 and lanthanum strontium cobalt nickel oxide La(0.50)Sr(0.50)Co(0.50)Ni(0.50)O3; LSCNO as candidate transparent electrodes for use in a shutter-based infrared sensor protection device. The shutter device requires that the electrode be transparent (80% transmission) and have moderate sheet resistance (300 ohms/sq.). Because of the effects of film thickness on intrinsic material properties, such as resistivity and extinction coefficient, and simple engineering issues (i.e., the relationship between film thickness, resistance and transmission), films of various thicknesses were prepared to achieve an optimal balance of electrical and optical performance. van der Pauw measurements and FTIR spectroscopy were used to study thin film properties. The best LSCO films prepared demonstrated electrical (438 ohms/sq.) and optical (68% transmission at 8 micrometers) properties that did not meet the target property goals for this application. However, the LSCNO films (of optimal thickness) offered performance (323 ohms/sq. and 73% transmission) close to the device requirements.
