Structural basis for the fast phase change of Ge$$_{2}$$Sb$$_{2}$$Te$$_{5}$$; Ring statistics analogy between the crystal and amorphous states

The three-dimensional atomic configuration of amorphous Ge$$_{2}$$Sb$$_{2}$$Te$$_{5}$$ were derived by reverse Monte Carlo simulation with synchrotron-radiation X-ray diffraction data. The authors found that amorphous Ge$$_{2}$$Sb$$_{2}$$Te$$_{5}$$ can be regarded as "even-numbered ring structure", because the ring statistics is dominated by four- and six-fold rings analogous to the crystal phase. On the other hand, the formation of Ge-Ge homopolar bonds in amorphous GeTe constructs both odd- and even-numbered rings. They believe that the unusual ring statistics of amorphous Ge$$_{2}$$Sb$$_{2}$$Te$$_{5}$$ is the key for the fast crystallization speed of the material.

Inelasticity effect on neutron scattering intensities of the null-H$$_{2}$$O

Kameda, Yasuo*; Sasaki, Motoya*; Usuki, Takeshi*; Otomo, Toshiya*; Ito, Keiji*; Suzuya, Kentaro; Fukunaga, Toshiharu*

Journal of Neutron Research, 11(3), p.153 - 163, 2003/09

We describe results of time-of-flight (TOF) neutron diffraction of the liquid water null-H$$_{2}$$O in order to investigate the effect of both the scattering angle and the neutron flight path ratio to the observed self-scattering intensities. An empirical inelasticity correction procedure is proposed using the self-scattering intensity observed for the null-H$$_{2}$$O.
