Anisotropic-gap and two-band effects smear out the superconducting transition (Tc) in literature reported thermal conductivity of MgB2, where large electronic contributions also suppress anomaly-manifestation in their negligible phononic-parts. Present thermal transport results on scarcely explored specimens featuring nano-inclusions exhibit a small but clear Tc-signature, traced to relatively appreciable phononic conduction, and its dominant electronic-scattering. The self-formed MgO as… 
Thermal conductivity of Mg(B0.94C0.06)2 superconductors: role of carrier and lattice–impurity scattering
We use the Kubo model to calculate the lattice contribution to the thermal conductivity (κph) in Mg(B0.94C0.06)2 superconductors. The theory is formulated when heat transfer is limited by the
Potential enhancement of superconductivity in MgB2 nanosheets: First-principles calculations
Abstract First-principles calculations based on density functional theory are performed on the three types of free-standing MgB 2 (0 0 0 1) nanosheets with different thickness and surface
Scattering effect of the well-ordered MgB4 impurity phase in two-step sintered polycrystalline MgB2 with glycine addition
Glycine-doped MgB2 bulk was prepared by two-step sintering in this study, first at 750 °C and then 900 °C. The MgB4 particles are induced to precipitate where the dislocations concentrated after C
Multiwalled carbon nanotube-derived superior electrical, mechanical and thermal properties in MgB2 wires
We investigated the effects of multiwalled carbon nanotubes (MWCNTs) as an additive on the critical current density, critical temperature, microstructure and thermal conductivity of MgB2 wires. These

The development of novel processing routes including thermal and mechanical treatments of metallic glasses is important for numerous structural and biomedical applications. In the first of several


Heat and charge transport properties of MgB2
Abstract A polycrystalline sample of the MgB 2 superconductor was investigated by measurements of the electrical resistivity, the thermopower and the thermal conductivity in the temperature range
Superconductivity of metallic boron in MgB2.
Band structure calculations indicate that Mg is substantially ionized, and the bands at the Fermi level derive mainly from B orbitals, and MgB2 can be viewed as an analog of the long sought, but still hypothetical, superconducting metallic hydrogen.
Thermal conductivity of Al-doped MgB2 : Impurity scattering and the validity of the Wiedemann-Franz law
We report data on the thermal conductivity K(T,H) along the basal plane of the hexagonal crystal structure of superconducting Mg{1-y}Al{y}B2 with y=0.02 and 0.07 at temperatures between 0.5 and 50 K
Two-band effects in the transport properties of MgB2
We present resistivity and thermal conductivity measurements on bulk samples, prepared either by a standard method or by a one-step technique. The latter samples, due to their high density and
Two-band superconductivity in MgB2.
The study of the anisotropic superconductor MgB2 using a combination of scanning tunneling microscopy and spectroscopy reveals two distinct energy gaps with both gaps vanishing at the bulk T(c) with the data confirming the importance of Fermi-surface sheet dependent superconductivity proposed in the multigap model.
Nanoscale-SiC doping for enhancing Jc and Hc2 in superconducting MgB2
The effect of nanoscale-SiC doping of MgB2 was investigated in comparison with undoped, clean-limit, and Mg-vapor-exposed samples using transport and magnetic measurements. It was found that there

High critical current density and enhanced irreversibility field in superconducting MgB2 thin films
It is shown that MgB2 thin films that are alloyed with oxygen can exhibit a much steeper temperature dependence of H*(T) than is observed in bulk materials, yielding an H* value at 4.2 K greater than 14 T.
Phonon localization in glasses.
The universal plateau in bulk glasses is associated with phonon localization due to strong scattering from inhomogeneities on this length scale, and Ioffe-Regel localization of the vibrational modes occurs for phonons whose wavelength and mean free path are on the order of a structural correlation length of the material.
