Cubic-Zn(1-x)Mn(x)Te optical modes across the phonon and phonon-polariton regimes
M. Mina, A. Elmahjoubi, T. Ngulezhu +18
Alloying offers a convenient route to tune the physical properties of semiconductors, at the price, however, of local lattice/bond distortions needed to accommodate the lattice mis…
When carbon impurities trigger the synthesis of alpha boron at high pressure and high temperature
Amrita Chakraborti, Yeonsoo Cho, Jelena Sjakste +5
The role of carbon in the formation of alpha boron at high pressure and high temperature (HPHT) has been investigated by combining HPHT experiments and density functional theory (D…
Pressure-induced structural phase transition and suppression of Jahn-Teller distortion in the quadruple perovskite structure
V. S. Bhadram, B. Joseph, D. Delmonte +5
By means of in situ synchrotron X-ray diffraction and Raman spectroscopy under hydrostatic pressure, we investigate the structural stability of the quadruple perovskite LaMn7O12. A…
Boron monosulfide: equation of state and pressure-induced phase transition
Kirill A. Cherednichenko, Ivan A. Kruglov, Artem R. Oganov +3
Quasi-hydrostatic compression of rhombohedral boron monosulfide (r-BS) has been studied up to 50 GPa at room temperature using diamond-anvil cells and angle-dispersive synchrotron…
Orthorhombic boron oxide under pressure: in situ study by X-ray diffraction and Raman scattering
Kirill A. Cherednichenko, Yann Le Godec, Aleksandr Kalinko +2
High-pressure phase of boron oxide, orthorhombic \b{eta}-B2O3, has been studied in situ by synchrotron X-ray diffraction to 22 GPa and Raman scattering to 46 GPa at room temperatur…
Melting of B12P2 boron subphosphide under pressure
Vladimir L. Solozhenko, Vladimir A. Mukhanov, Petr S. Sokolov +3
Melting of boron subphosphide (B12P2) to 26 GPa has been studied by in situ synchrotron X-ray powder diffraction in a laser-heated diamond anvil cell, and by quenching and electric…
Equation of state of single-crystal cubic boron phosphide
Yann Le Godec, Mohamed Mezouar, Oleksandr O. Kurakevych +4
The 300 K equation of state of cubic (zinc-blende) boron phosphide BP has been studied by in situ single-crystal X-ray diffraction with synchrotron radiation up to 55 GPa. The meas…
Self-propagating high-temperature synthesis of boron phosphide
Vladimir A. Mukhanov, Petr S. Sokolov, Yann Le Godec +1
A new method of producing boron phosphide (BP) submicron powders by self-propagating high-temperature reaction between boron phosphate and magnesium in the presence of an inert dil…
Comparison of solid state crystallization of boron polymorphs at ambient and high pressures
Oleksandr O. Kurakevych, Yann Le Godec, Tahar Hammouda +1
Here we report the systematic study of solid-state phase transformations between boron polymorphs: α-B12, β-B106, γ-B28, T-B52 and amorphous boron (am-B). It is evident that the Os…
Comment on Zarechnaya et al. Pressure-induced isostructural phase transformation in gamma-B28. Phys. Rev. B 82, 184111 (2010)
Yann Le Godec, Artem R. Oganov, Oleksandr O. Kurakevych +1
Zarechnaya et al. claimed an isostructural transformation in gamma-B28 at about 40 GPa; below which the phase is more compressible (B0=227 GPa) and above which less compressible (B…
The high-pressure phase of boron, γ-B28: disputes and conclusions of 5 years after discovery
Artem R. Oganov, Vladimir L. Solozhenko, Carlo Gatti +2
γ-B28 is a recently established high-pressure phase of boron. Its structure consists of icosahedral B12 clusters and B2 dumbbells in a NaCl-type arrangement (B2)δ+(B12)δ- and displ…
