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 ...

Limitation of Fermi level shifts by polaron defect states in hematite photoelectrodes. [PDF]
Nat Commun, 2018 The optical band gap is a major selection criterion for an absorber in photocatalytic water splitting. Due to its ideal value hematite has been intensively investigated without reaching the expectation, yet.

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 ...

Width-Dependent Band Gap in Armchair Graphene Nanoribbons Reveals Fermi Level Pinning on Au(111). [PDF]
ACS Nano, 2017 We report the energy level alignment evolution of valence and conduction bands of armchair-oriented graphene nanoribbons (aGNR) as their band gap shrinks with increasing width.

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

Multi peak emission and morphological evolution of Fe-doped ZnOs nanoflowers [PDF]
Processing and Application of Ceramics, 2023 The nanoflowers and nanoblocks of Fe-doped ZnO (i.e. ZnO doped with 0, 1, 2, 3, 4 and 5% Fe) were synthesised by co-precipitation technique. XRD analysis showed that the samples have wurtzite structure containing mostly Fe3+ in the samples with 1% Fe and

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 ...
