Phys. Rev. Lett. 102, 035502 (2009) [5 pages]Coherent-Pulse 2D Crystallography Using a Free-Electron Laser X-Ray Source
Received 24 September 2008; published 22 January 2009
Coherent diffractive imaging for the reconstruction of a two-dimensional (2D) finite crystal structure with a single pulse train of free-electron laser radiation at 7.97 nm wavelength is demonstrated. This measurement shows an advance on traditional coherent imaging techniques by applying it to a periodic structure. It is also significant that this approach paves the way for the imaging of the class of specimens which readily form 2D, but not three-dimensional crystals. We show that the structure is reconstructed to the detected resolution, given an adequate signal-to-noise ratio. ©2009 The American Physical Society REFERENCES (30)
