Fermi level tuning of Ag-doped Bi2Se3 topological insulator. [PDF]
Sci Rep, 2019 The temperature dependence of the resistivity (ρ) of Ag-doped Bi2Se3 (AgxBi2−xSe3) shows insulating behavior above 35 K, but below 35 K, ρ suddenly decreases with decreasing temperature, in contrast to the metallic behavior for non-doped Bi2Se3 at 1.5 ...

Estimating the quasi-Fermi level of holes at the surface of semiconductor photoanodes using outer-sphere redox couples [PDF]
Nature CommunicationsSemiconductor electrodes can catalyze photo-induced redox reactions with light illumination. Photoexcitation produces excited carriers that subsequently transfer to the front and back contacts as determined by the bulk and surface properties of the ...

Level Density of a Fermi Gas: Average Growth and Fluctuations [PDF]
Physical Review Letters, 2006 We compute the level density of a two-component Fermi gas as a function of the number of particles, angular momentum, and excitation energy. The result includes smooth low-energy corrections to the leading Bethe term (connected to a generalization of the partition problem and Hardy-Ramanujan formula) plus oscillatory corrections that describe shell ...

Exact solutions for the periodic Anderson model in 2D: A Non-Fermi liquid state in normal phase [PDF]
, 2001 Presenting exact solutions for the two dimensional periodic Anderson model with finite and nonzero on-site interaction U>0, we are describing a rigorous non-Fermi liquid phase in normal phase and 2D. This new state emerges in multi-band interacting Fermi systems above half filling, being generated by a flat band effect.

Non-symmorphic band degeneracy at the Fermi level in ZrSiTe [PDF]
New Journal of Physics, 2016 Non-symmorphic materials have recently been predicted to exhibit many different exotic features in their electronic structures. These originate from forced band degeneracies caused by the non-symmorphic symmetry, which not only creates the possibility to

Excitation Spectrum and Stability from a Filled Landau Level in Rotating Dipolar Fermi Gases [PDF]
arXiv, 2008 We apply the equation-of-motion method to study the collective excitation spectrum from a filled Landau level in rotating dipolar Fermi gases. The predicted excitation spectrum of rotating dipolar Fermi gases can exhibit a roton-minimum character. This roton character is tunable by varying the dipole interaction strength and confining potential.
