Introduction IV-VI compounds are regarded as average group V material. In crystalline group V elements and IV-VI compounds, the Peierls distortion occurs. Strong bonds with short bond length and relatively weak bonds with long bond length coexist in the crystal. Therefore anisotropic contraction of the local structure is expected under pressure [1]. In crystalline SnSe, atoms form two dimension...
A novel analysis method for the direct retrieval of real-space distribution charged particle pairs from liquid-phase electron scattering.
The liquid state is the most complex phase of matter. Densities of liquids are comparable to densities of the solids, implying that the forces between particles in the liquid are of the samemagnitude as those forces present in the solid. However, there is no simplification due to the presence of a lattice and no satisfactory analytic theory of the liquid state exists. However, despite this comp...
The short-range order (SRO) in Pd78Cu6Si16 liquid was studied by high energy x-ray diffraction and ab initio molecular dynamics (MD) simulations. The calculated pair correlation functions at different temperatures agree well with the experimental results. The partial pair correlation functions from ab intio MD simulations indicate that Si atoms prefer to be uniformly distributed while Cu atoms ...
Understanding the atomic structure of amorphous solids is important in predicting and tuning their macroscopic behavior. Here, we use a combination of high-energy X-ray diffraction, neutron diffraction, and molecular dynamics simulations to benchmark the atomic interactions in the high temperature stable liquid and low-density amorphous solid states of hafnia. The diffraction results reveal an ...
