Abstract

The production of mirrors to operate at very short X-ray wavelengths (2-5 nm) still provides a challenge for materials scientists. The need for smooth interfaces whilst maintaining a considerable compositional sharpness is inherently problematic, since the former requires layers which are in some way compatible and by implication mutually soluble, whilst the latter is more likely to be achieved when two elements are immiscible.
