X-ray standing wave induced Compton and elastic scattering from thin periodic multilayer structures

Atomic separation in Co/Cu/Co magnetic structures study by hybrid X-ray reflectivity – X-ray standing wave approach

“…The wave modulations are typical for the X-ray waveguide structures that are typically observed for specially designed samples [20,21] as it increases significantly the in-depth sensitivity of the XSW analysis. This effect was used, for example, for the increase of the analysis sensitivity to the density of ultra-thin films [22] structure of magnetic layers [23]. For our samples, the waveguide was formed by the sample as is without any explicit design.…”

Quantum Confinement Effect in a Nanoscale Mo/Si Multilayer Structure

“…Multilayer films prepared by properly selected alternate nanolayers are broadly used as reflective mirrors for several applications. − In particular, the Mo/Si multilayers are widely used for nanolithography, soft X-ray/EUV microscopy, and solar astronomy. − Microscopic structures of interfaces are critical for obtaining the effective reflection coefficient, which, in the first place, mostly depends on the atomic density contrast and the value of β (thickness ratio of the Mo layer to the multilayer period d , i.e., β = d Mo / d ). Understanding the microscopic details including electronic and quantum mechanical properties of the multilayers is fundamentally important, which will be further useful in future to design high-efficiency mirrors.…”
