X-ray diffraction data for a-GeSe₂ at ambient (bottom) and under high-pressure conditions (patterns are vertically shifted for clarity). In the inset we report a typical diffraction image, showing the intense ring from the nano-polycrystalline diamonds, a broad halo from the sample and two weak rings from the gasket (stainless steel), one of them being highlighted from the asterisk in the plot. The signal from the sample corresponds to the main peak of the structure factor, which is seen to shift to higher angles with the applied pressure. No sign of crystallization has been found up to 32.5 GPa.
