Two-dimensional (2D) Cr-based layered and non-layered materials such as CrI3, Cr2Ge2Te6, Cr2S3, CrSe, CrOX (X = Cl Br) have attracted considerable attention due to their potential application in spintronics. Despite few experimental studies, theoretical studies reported that 2D chromium dichalcogenide (CrS2) show unique properties valley polarization, piezoelectric coupling, phase dependent intrinsic magnetic properties. Here, we report for the first time synthesis of CrS2 flakes down...
We observe synergistic photoluminescence of MoS<sub>2</sub>/PTCDA vdW heterostructure due to the interface interaction and improved crystal PTCDA layer.
The use of MoS2 nanosheets as a gas sensing material has been reported extensively in recent years. Sulfur vacancies (VS) are known to play significant role, but the detailed mechanism is still dispute. In this work, we tried investigate relationship between VS and response based on experimental simulation results. Experimentally, developed NO2 sensor liquid-exfoliated with 330% at 100 °C for 5 ppm gas. excellent performance due creation sulfur (undercoordinated Mo atoms) room temperature....
To fabricate stable and high-quality graphene–silicon (Si) heterojunctions, it is of paramount importance to grow graphene on pristine Si surfaces directly understand its growth mechanism.

Abstract 2D transition metal dichalcogenides (TMDs) are a promising material system for optoelectronic applications. However, their key figure of merit, the room‐temperature photoluminescence (PL), is extremely low. To overcome this challenge, TMDs need interfacing with other semiconducting materials and discover underlying physical phenomena. Herein, optical properties PL mechanisms molybdenum disulfide‐organic perylene derivative (PDI/MoS 2 ) based type‐II heterostructures, i.e., PTCDA/MoS...

Limited calculations show that monolayer (ML) chromium dichalcogenide (CrS 2 ) has a direct bandgap and valley polarization but with smaller than ML MoS distinct piezoelectric ferromagnetic properties. It is highly desirable to determine an appropriate metal contact for novel two‐dimensional (2D) CrS ‐based devices. By using density functional theory (DFT), the interface between commonly used metals, including s ‐electron d studied systematically by evaluating binding energy, Schottky...
