Fabrication of high-performance optoelectronic devices is an important aspect of the application research of transition metal dichalcogenides (TMDCs). In this study, heterostructures of TMDCs and hexagonal boron nitrides (hBN) were successfully fabricated into light-emitting devices. Monolayer and artificially stacked homobilayer WS2 were prepared ...

Heterogeneous stacking based on two-dimensional Ruddlesden–Popper (RP) perovskite is a desired strategy for the reasonable combination of stability and efficiency. Constructing heterostructures with tunable optoelectronic properties further provide opportunities to design multi-functional devices. Herein, we present a first-principle research to in...

Breakdown voltage enhancement was studied for p-GaN/AlGaN/GaN heterostructure diodes, where residual Si donors during growth were compensated with Mg acceptors doped in the p-GaN layer. As the thicknesses of the p-GaN layer (T p-GaN) decreased from 140 nm, breakdown voltages were increased and maximized at 20 nm, then decreased at 0 nm. Moreover, b...

It is of great significance to design highly efficient electrocatalysts with abundant earth elements instead of precious metals for water splitting. Herein, Mo-doped NiFe-layered double hydroxides/NiSe heterostructure (Mo-NiFe LDH/NiSe) was fabricated by coupling Mo-doped NiFe LDH and NiSe on nickel foam (NF). The heterostructure electrocatalyst sh...

Inorganic perovskites have been recognized as highly potent materials for the display and medical industries due to their outstanding features. However, there haven’t been many reports on their implications as a photocatalyst for the removal of heavy metals. Photocatalysis has been regarded as a significant approach for the removal of pollutants be...
