Graphene-based tunable linear and linear-to-circular polarization converters in the THz band

Results in Physics, 2022
A switchable and tunable reflective terahertz (THz) polarization converter based on graphene metamaterial is designed and analyzed. By changing the Fermi energy level of graphene, the converter can achieve broadband linear polarization conversion (LPC ...

Asymptotic Pomeranchuk instability of Fermi liquids in half-filled Landau levels

Scientific Reports, 2023
We present a theory of spontaneous Fermi surface deformations for half-filled Landau levels (filling factors of the form $$\nu =2 \, n+1/2$$ ν = 2 n + 1 / 2 ).

Anomalous self-energy and Fermi surface quasi-splitting in the vicinity of a ferromagnetic instability [PDF]

, 2004
We discuss the low-temperature behavior of the electronic self-energy in the vicinity of a ferromagnetic instability in two dimensions within the two-particle self-consistent approximation, functional renormalization group and Ward-identity approaches ...

On the Relation between the Open‐Circuit Voltage and Quasi‐Fermi Level Splitting in Efficient Perovskite Solar Cells

Advanced Energy Materials, 2019
Today's perovskite solar cells (PSCs) are limited mainly by their open‐circuit voltage (VOC) due to nonradiative recombination. Therefore, a comprehensive understanding of the relevant recombination pathways is needed.

Giant anomalous Nernst effect in the Co2MnAl1−xSix Heusler alloy induced by Fermi level tuning and atomic ordering [PDF]

Physical review B, 2019
Co2MnAl has been predicted to have Weyl points near Fermi level which is expected to give rise to exotic transverse transport properties such as large anomalous Hall(AHE) and Nernst effects(ANE) due to large Berry curvature.

Charge transport across metal/molecular (alkyl) monolayer-Si junctions is dominated by the LUMO level

, 2011
We compare the charge transport characteristics of heavy doped p- and n-Si-alkyl chain/Hg junctions. Photoelectron spectroscopy (UPS, IPES and XPS) results for the molecule-Si band alignment at equilibrium show the Fermi level to LUMO energy difference ...

Topological Type-II Dirac Fermions Approaching the Fermi Level in a Transition Metal Dichalcogenide NiTe2 [PDF]

, 2018
Type-II Dirac/Weyl semimetals are characterized by strongly tilted Dirac cones such that the Dirac/Weyl node emerges at the boundary of electron and hole pockets as a new state of quantum matter, distinct from the standard Dirac/Weyl points with a point ...
