First-principles investigation of nonmetal doped single-layer BiOBr as a potential photocatalyst with a low recombination rate

Abstract

Nonmetal doping is an effective approach to modify the electronic band structure and enhance the photocatalytic performance of bismuth oxyhalides.

Oxygen Vacancies in the Single Layer of Ti2CO2 MXene: Effects of Gating Voltage, Mechanical Strain, and Atomic Impurities

“…Several approaches have been considered to change the electronic structure of 2DM, such as substitutional doping, defect engineering, application of an electric field or strain, surface functionalization by adatoms, and altering the edge states. [ 37–78 ]…”

Preparation of perovskite CsPb(BrxI1−x)3quantum dots at room temperature

“…As the content of the I element increases, the diffraction peaks of the perovskite crystal tend to a low angular offset. Besides, different proportions of CsPb(Br x I 1Àx ) 3 QDs also exhibit a cubic phase at low temperatures. The movement of the position of the main peaks is regular, so the substitution of anions in the perovskite structure does not change its phase signicantly.…”

“…1 As is well-known, both ion exchange and doping affect the electronic band structure. [2][3][4] Therefore, depending on the combination of these anions and cations, perovskite materials can exhibit different characteristics, such as superconductivity, piezoelectric, insulating, antiferromagnetic, and photoelectric properties. [5][6][7][8] So far, these nanomaterials have been demonstrated as promising building blocks for solar cells, exible sensors, and silicon-based photonics, and they are even expected to be used in biological detection and electrically driven lasers.…”

A Biaxial Strain Sensor Using a Single MoS2 Grating

“…Following the introduction of grapheme [12,13], the family of 2D materials has been enlarged by many new members such as double atomic thin black phosphorus [14], triple atomic thin transition metal dichalcogenides [15], quadruple atomic thin group-III metal monochalcogenides [16], and other nonlayered 2D materials [17]. Many interesting properties have been found in these materials, keeping them under the spotlight of materials science [18][19][20][21][22][23][24].…”
