“…The calculated q th (T) in Al overestimates at the lower temperatures due to the neglection of the lattice contribution to the thermal conduction. LOVA is expected to be a good approximation within the temperature range of H D /5 < T < 2H D [8,34,35]. This range including the room temperature is of special importance in the technological applications of metals.…”

Transport properties, temperature-dependent phonon-limited electrical and thermal resistivities in the normal state of two-dimensionally (2D) infinite-fused zinc porphyrin with a directly meso-meso-, b-b-, and b-b-linked array structure ZnP 1 were theoretically calculated using linear-response approach based on density functional theory (DFT). The calculated transport electron-phonon coupling (EPC) constant using the density functional perturbation theory (DFPT) shows almost equal to the superconducting EPC constant, which is the similar situation within a difference by ca. 10% between them for the transition metals. The calculated electrical and thermal resistivities at 300 K obtained by solving the Boltzmann equation within the lowestorder variational approximation (LOVA) are only larger by one digit than those of the reference metal Al, expecting to become a fantastic 2D synthetic metal without an injection of conductive carriers from outside, e.g., by doping. The calculated results for the 2D infinite-fused lithium porphyrin LiP 1 with the same ground state as the oneelectron oxidative state of ZnP 1 were also discussed for comparison. This simple approach using the first applied plane-wave ultrasoft pseudopotentials (US-PPs) is a usable technique for the prediction of the transport properties of simple metallic materials within the practical temperature range.

“…The k tr and k sc differ in generally by only ca. 10% for the transition metals [5,6,25,34,35], whose trend is also fitting to ZnP 1 . On the other hand, LiP 1 shows a meaningful difference between k tr and k sc , such as the reference Al, whose reason would be discussed in following sections.…”

When viewed at frequencies below about 8 THz (250 cm −1 ; 30 meV) the ab-plane optical conductivity of the cuprate superconductors (in their normal state) is well described by a Drude model. Examples include optimally-doped YBa2Cu3O 7−δ and Bi2Sr2CaCu2O8; even the underdoped phases have a Drude character to their optical conductivity. A residual Drude-like normal fluid is seen in the superconducting state in most cases; the scattering rate of this quasiparticle contribution collapses at Tc.

“…tr λ and λ usually agree to within 10% for d band metals, 37,52 so we approximate tr λ by λ , which is obtained from electronic tunneling data and McMillan's formula for c T . 34 We attempt to use our calculations to reproduce the experimental resistivities of all the studied bcc metals (except Cr) over a defined temperature range.…”

In order to predict the stable and metastable phases of the bcc metals in the block of the Periodic Table defined by groups 5B to 6B and periods 4 to 6, as well as the structure dependence of their transport properties, we have performed full potential computations of the total energies per unit cell as a function of the a c ratio at constant experimental volume. In all cases, a metastable body centered tetragonal (bct) phase was predicted from the calculations. The total energy differences between the calculated stable and metastable phases ranged from 0.09 eV/cell (vanadium) to 0.39 eV/cell (tungsten). The trends in resistivity as a function of structure and atomic number are discussed in terms of a model of electron transport in metals. Theoretical calculations of 2 the electrical resistivity and other transport properties show that bct phases derived fromgroup 5B elements are more conductive than the corresponding bcc phases, while bct phases formed from group 6B elements are less conductive than the corresponding bcc phases. Special attention is paid to the phases of tantalum where we show that the frequently observed β phase is not a simple tetragonal distortion of bcc tantalum.
