Exotic centrosymmetric phase of acentric urea under high pressure
Haw-Tyng Huang, Yedukondalu Neelam, Mei-Shuan Cheng +6
Urea is a simple prototype supramolecular crystal that exhibits rich polymorphism at low pressure due to broken and restored N-H-O hydrogen bonds. The high pressure polymorph (phas…
Lattice Instability and Ultralow Lattice Thermal Conductivity of Layered PbIF
N. Yedukondalu, Aamir Shafique, S. C. Rakesh Roshan +5
Understanding the interplay between various design strategies (for instance, bonding heterogeneity and lone pair induced anharmonicity) to achieve ultralow lattice thermal conducti…
Lattice instability, anharmonicity and Raman spectra of BaO under high pressure: A first principles study
K. Lavanya, N. Yedukondalu, S. C. Rakesh Roshan +5
Alkaline-earth metal oxides, in particular MgO and CaO dominate Earths lower mantle, therefore, exploring high pressure behavior of this class of compounds is of significant geophy…
Anomalous Lattice Thermal Conductivity in Rocksalt IIA-VIA Compounds
S. C. Rakesh Roshan, N. Yedukondalu, Rajmohan Muthaiah +6
Materials with an intrinsic (ultra)low lattice thermal conductivity (k) are critically important for the development of efficient energy conversion devices. In the present work…
The high-pressure alpha/beta phase transition in lead sulphide (PbS): X-ray powder diffraction and quantum mechanical calculations
K. Knorr, L. Ehm, M. Hytha +2
The high-pressure behaviour of PbS was investigated by angular dispersive X-ray powder diffraction up to pressures of 6.8 GPa. Experiments were accompanied by first principles calc…
The pseudo-binary mercury chalcogenide alloy HgSe0.7S0.3 at high pressure: a mechanism of the zinc blende/cinnabar reconstructive phase transition
D. P. Kozlenko, K. Knorr, L. Ehm +4
The structure of the pseudo-binary mercury chalcogenide alloy HgSe0.7S0.3 has been studied by means of X-ray and neutron powder diffraction at pressures up to 8.5 GPa. A phase tran…
