X-ray linear dichroism of defects in GaN:Mg using hard x-ray nanoprobe

Applied Physics Letters, 2009
In this study, we report the application of synchrotron radiation nanoprobe techniques to the structural analysis of pyramidal defects in Mg doped GaN. A combination of fluorescence mapping with spectroscopic techniques enabled us to examine not only the elemental nature but also their crystallographic orientation on the submicron scale.

Optimization of a multilayer Laue lens system for a hard x-ray nanoprobe

Journal of Optics, 2013
Detailed designs of a multilayer Laue lens system for a hard x-ray nanoprobe, including flat and wedged types, are presented, to realize nanoscale point focus and high diffraction efficiency simultaneously. The difficulty of movement and alignment for lens, aperture and sample are considered in the optimization process.

Design of a Hard X-Ray Nanoprobe based on FZP

A high-resolution hard X-ray nanoprobe (HXNP) based on Fresnel Zone plate (FZP) was designed. The HXNP relies on a compact, high stiffness, low heat dissipation and low vibration design philosophy and utilizes FZP as nanofocusing optics. The optical layout and overall mechanical design of the HXNP were introduced.

Hard x-ray nanoprobe by Montel KB mirrors at Taiwan Photon Source

SPIE Proceedings, 2015
The hard X-ray nanoprobe at Taiwan Photon Source (TPS) makes use of the large numerical aperture obtained by nested Montel mirrors. To fully uptake the focusing power and flux, these mirrors requires the surface slope error no less than 0.05 μrad and are symmetrically placed with a 45 degrees cut for perfect surface matching.
