Influence of Fermi Level Alignment with Tin Oxide on the Hysteresis of Perovskite Solar Cells.

open access: yesACS Applied Materials and Interfaces, 2018
We tune the Fermi level alignment between the SnO x electron transport layer (ETL) and Cs0.05(FA0.83MA0.17)0.95Pb(I0.83Br0.17)3 and highlight that this parameter is interlinked with current-voltage hysteresis in perovskite solar cells (PSCs). Furthermore,

Electronic properties and Fermi surface of Ag(111) films deposited onto H-passivated Si(111)-(1x1) surfaces

open access: yes, 2001
Silver films were deposited at room temperature onto H-passivated Si(111) surfaces. Their electronic properties have been analyzed by angle-resolved photoelectron spectroscopy.

Improved Schottky junction analysis model

open access: yesFunctional Diamond
The intersection of the Fermi and impurity levels in the Schottky junction of boron-doped p-type diamond, a widely used p-type doping scheme for diamond, has been discovered. This indicates that the relationship between the ionization efficiency of boron

Mechanism and Verification of Photoelectric Regulation Characteristics of Two-Dimensional Photodetectors

open access: yesIEEE Photonics Journal
Two-dimensional photodetectors have an important property that can improve the optical effect by adjusting the Fermi level, and have outstanding development prospects in the field of visible-infrared photoelectric detection.

Terahertz Multiple Beam Steering Using Graphene Pancharatnam-Berry Metasurfaces

open access: yesIEEE Photonics Journal, 2022
Pancharatnam-Berry metasurfaces have the great advantage of manipulating electromagnetic wave. At the same time, graphene has attracted much attention due to its unique electromagnetic responses in different Fermi levels.

Continuous transitions between composite Fermi liquid and Landau Fermi liquid: a route to fractionalized Mott insulators

open access: yes, 2012
One of the most successful theories of a non-Fermi liquid metallic state is the composite Fermi liquid (CFL) theory of the half-filled Landau level. In this paper, we study continuous quantum phase transitions out of the CFL state and into a Landau Fermi

Reduction of Schottky Barrier Height at Graphene/Germanium Interface with Surface Passivation

open access: yesApplied Sciences, 2019
Fermi level pinning at metal/semiconductor interfaces forbids a total control over the Schottky barrier height. 2D materials may be an interesting route to circumvent this problem. As they weakly interact with their substrate through Van der Waals forces,

Rich nature of Van Hove singularities in Kagome superconductor CsV3Sb5

open access: yesNature Communications, 2022
Predictions suggest enhanced correlation effect due to multiple van Hove singularities (VHS) in the vicinity of the Fermi level in the recently discovered AV3Sb5 kagome metals.

Fermi level pinning at the Ge(001) surface - A case for non-standard explanation

open access: yes, 2015
To explore the origin of the Fermi level pinning in germanium we investigate the Ge(001) and Ge(001):H surfaces. The absence of relevant surface states in the case of Ge(001):H should unpin the surface Fermi level. This is not observed.

The Fermi surface of underdoped high-T_c superconducting cuprates

open access: yes, 1997
The coexistence of $\pi$-flux state and d-wave RVB state is considered in this paper within the slave boson approach. A critical value of doping concentration $\delta_c$ is found, below which the coexisting $\pi$-flux and d-wave RVB state is favored in ...
