A multilayer (sputtered-sliced) Fresnel zone plate (FZP) is one of the promising focusing optics with high spatial resolution for the high-energy X-ray region. This is because a large “aspect ratio” can be realized easily. In addition, it is impo

The interface reaction between poly-Si and high- k dielectrics (including HfSiON and HfAlO) have been investigated using hard X-ray ( hν = 5.95 keV) photoemission spectroscopy (HX-PES). HX-PES method has enabled us to probe intrinsic interfacial sta
