Fermi Level Equilibration at the Metal-Molecule Interface in Plasmonic Systems. [PDF]
Nano letters (Print), 2021 We highlight a new metal-molecule charge transfer process by tuning the Fermi energy of plasmonic silver nanoparticles (AgNPs) in situ. The strong adsorption of halide ions upshifts the Fermi level of AgNPs by up to ∼0.3 eV in the order Cl- < Br- < I ...

Ferroelectrically modulate the Fermi level of graphene oxide to enhance SERS response
Opto-Electronic Advances, 2023 Surface-enhanced Raman scattering (SERS) substrates based on chemical mechanism (CM) have received widespread attentions for the stable and repeatable signal output due to their excellent chemical stability, uniform molecular adsorption and controllable ...

Band structure of organic-ion-intercalated (EMIM)$_x$FeSe superconductor [PDF]
Materials 15, 1856 (2022), 2022 The band structure and the Fermi surface of the recently discovered superconductor (EMIM)$_x$FeSe are studied within the density functional theory in the generalized gradient approximation. We show that the bands near the Fermi level are formed primarily by Fe-$d$ orbitals.

Fermi Level Position at Semiconductor Surfaces [PDF]
Physical Review Letters, 1963 There have been several recent reports of barrier height studies on metal-semiconductor interfaces. Metals of widely different work functions evaporated onto Si and GaAs surfaces indicated that in each case the energy difference between the semiconductor conduction band edge and Fermi level at the interface,φ_(Bn), was essentially independent of the

Mechanism of Fermi-level stabilization in semiconductors [PDF]
Physical Review B, 1988 A striking correlation between the Fermi level in heavily radiation damaged semiconductors and at metal-semiconductor interfaces is presented. The correlation provides critical evidence supporting the defect model for Schottky-barrier formation. The Fermi-level energy for both situations corresponds to the average energy of the ${\mathrm{sp}}^{3 ...
