Metal to Orthogonal Metal Transition [PDF]
Chinese Physics Letters, 2020 Orthogonal metal is a new quantum metallic state that conducts electricity but acquires no Fermi surface (FS) or quasiparticles, and hence orthogonal to the established paradigm of Landau's Fermi-liquid (FL).

Transition metal-like carbocatalyst [PDF]
Nature Communications, 2020 Metal-free catalysts can offer uniquely different activity and selectivity from transition metal-based counterparts. Here, the authors report metal-free nitrogen-assembly carbon with closely-placed nitrogen as active sites, achieving catalytic cleavage ...

Energy Transition Metals [PDF]
IMF Working Papers, 2021 The energy transition requires substantial amounts of metals such as copper, nickel, cobalt and lithium. Are these metals a key bottleneck? We identify metal-specific demand shocks, estimate supply elasticities and pin down the price impact of the energy transition in a structural scenario analysis.

Transition-metal nitride halide dielectrics for transition-metal dichalcogenide transistors [PDF]
Nanoscale, 2022 Using first-principles calculations, we investigate six transition-metal nitride halides as potential vdW dielectrics for transition metal dichalcogenide channel transistors. We identify the best combinations for the p-MOS transistor technology.

Room-temperature-superconducting T c driven by electron correlation
Scientific Reports, 2021 Room-temperature-superconducting T c measured by high pressure in hydrides can be theoretically explained by a Brinkman–Rice (BR)–Bardeen–Cooper–Schrieffer (BCS) T c combining both the generalized BCS T c and the diverging effective mass, m*/m = 1/(1 ...

Transition metal transport [PDF]
FEBS Letters, 2007 Transition metal transporters are of central importance in the plant metal homeostasis network which maintains internal metal concentrations within physiological limits. An overview is given of the functions of known transition metal transporters in the context of the unique chemical properties of their substrates.

Insulator-to-metal transition in ultrathin rutile VO2/TiO2(001)
npj Quantum Materials, 2022 An insulator-to-metal transition (IMT) is an emergent characteristic of quantum materials. When the IMT occurs in materials with interacting electronic and lattice degrees of freedom, it is often difficult to determine if the energy gap in the insulating

Approximating metal–insulator transitions [PDF]
International Journal of Modern Physics B, 2015 We consider quantum wave propagation in one-dimensional quasiperiodic lattices. We propose an iterative construction of quasiperiodic potentials from sequences of potentials with increasing spatial period. At each finite iteration step, the eigenstates reflect the properties of the limiting quasiperiodic potential properties up to a controlled maximum

Metal-insulator transition in transition metal dichalcogenide heterobilayer moiré superlattices [PDF]
Physical Review B, 2021 Moir superlattices formed in two-dimensional semiconductor heterobilayers provide a new realization of Hubbard model physics in which the number of electrons per effective atom can be tuned at will. We report on an exact diagonalization study of the electronic properties of half-filled narrow moir bands in which correlation strengths are varied by ...
