Intriguing electronic, optical and photocatalytic performance of BSe, M2CO2 monolayers and BSe–M2CO2 (M = Ti, Zr, Hf) van der Waals heterostructures

Using density functional theory calculations, we have investigated the electronic band structure, optical and photocatalytic response of BSe, M2CO2 (M = Ti, Zr, Hf) monolayers and their corresponding BSe–M2CO2 (M = Ti, Zr, Hf) van der Waals heterostructures.

Water Assisted Growth of Two-Dimensional MoS2/MoSe2 Vertical Heterostructures on Molten Glass

Herein, we demonstrate a chemical vapor deposition route to controlled growth of large scale MoS2/MoSe2 vertical van der Waals heterostructures on molten glass substrate using water as the oxidizing chemical...

First-principles study on optoelectronic properties of Cs2PbX4–PtSe2 van der Waals heterostructures

Energy level graphs of the monolayer PtSe2 and Cs2PbX4 in the (a) precontact and (b) contact. The Cs2PbBr4–PtSe2 heterostructure has a type-II level alignment which is conducive to spontaneously driving the holes and electrons to move forward in opposite directions.

An ultrafast photodetector driven by interlayer exciton dissociation in a van der Waals heterostructure

We model interlayer exciton transport in van der Waals heterostructures to propose devices based on interlayer exciton dissociation in split-gate geometries for ultrafast photodetector applications.

Highly Conjugated Three-Dimensional van der Waals Heterostructures Based Nanocomposite Films for Ultrahigh-Responsivity TEA Gas Sensors at Room Temperature

Covalent organic frameworks (COFs) have emerged as next-generation materials with predesigned π-electronic skeletons and highly ordered topological structures, which are promising for rapid gas sensing detection. COFs combined with carbon...
