TY - JOUR PY - 2008// TI - Normal-incidence silicon-gadolinium multilayers for imaging at 63 nm wavelength JO - Optics letters A1 - Kjornrattanawanich, B. A1 - Windt, D.L. A1 - Seely, J.F. SP - 965 EP - 967 VL - 33 IS - 9 N2 - Si/Gd multilayers designed as narrowband reflective coatings near 63 nm were developed. The highest peak reflectance of 26.2% at a 5° incident angle was obtained at 62 nm, and the spectral bandwidth was 7.3 nm FWHM. The fits for x-ray and extreme ultraviolet reflectance data of Si/Gd multilayers indicate the possibility of suicide formation at the Si-Gd interfaces. B4C, W, and SiN were deposited as interface barrier layers to improve the reflectance of Si/Gd multilayers. More than an 8% increase in reflectance was observed from the interface-engineered Si/W/Gd and Si/B4C/Gd multilayers. © 2008 Optical Society of America.
