Investigation of the structural, electronic, mechanical, and optical properties of NaXCl3 (X = Be, Mg) using density functional theory

“…In perovskite compounds, the X site is typically occupied by either oxide or halide ions. [1][2][3] Perovskites are a category of compounds known for their distinct crystal structure and remarkable physical and chemical properties. 4,5 These materials have attracted signicant attention from researchers due to their exible structure and exceptional electromagnetic, elastic, thermal, and electrical behaviors.…”

Bipolar Photoresponse of a Graphene Field-Effect Transistor Induced by Photochemical Reactions

“…For these reasons, graphene has been widely applied in photodetectors, solar cells, healthcare biosensors, chemical sensors, and flexible electronics . Recently, graphene and its derivatives have been vigorously attracted as electrode materials for energy storage devices. − The graphene, however, manipulating graphene characteristics requires the use of advanced techniques, thereby, graphene doping is a widely used method for fine-tuning of graphene work function and enhancing its electronic and hot electron photoelectric properties. − The tuning of the Fermi level of graphene through electrostatic doping, metallic nanoparticles decoration, and electrochemical doping is a widely used approach to control its structural, optical, pattern recognition, and electrical transport properties. − Moreover, chemical doping is considered the simplest and effective method for enhancing the electronic characteristics of 2D materials. − Although pure graphene exhibits an ambipolar field effect, it is not air-stable and is susceptible to unintended doping by compounds absorbed from the environment or residual compounds employed during device fabrication . Most graphene-based transistors with an ambipolar field effect are tested in a vacuum, argon, or nitrogen atmosphere where water or other contaminants have meager impact on the electrical properties of graphene.…”

Synergistic Effect of Hybrid CdSe Nanobelt/PbI2 Flake Heterojunction Toward Drastic Performance Flexible Photodetectors

“…In order to overcome the constraints of electronics relying on 2D PbI 2 material, mixed-dimensional heterostructures, as a possible solution for future multifunctional platforms, are assumed to be a convenient and effective approach. − Compared to the individual material, a mixed-dimensional heterostructure not only manifests the intrinsic properties of both individual components, as well as displays the extra desirable characteristics as a result of interplay at each component’s interface. − Low cost CdSe, as an important photoelectric chalcogenide of the II–VI group with a direct bandgap of ∼1.74 eV at room temperature, is widely explored in optoelectronics due to its excellent optical and electrical characteristics. − Among other morphologies of CdSe, a distinct 1D nanobelt like morphology with a rectangular shape at the edges has been widely studied in photodetectors. ,− Thus, the present study integrates the distinct properties of the aforementioned sensing materials to fabricate a well performing 1D/2D hybrid heterojunction photodetector. To date, there is no available approach for the fabrication of broadband flexible photodetectors utilizing a single crystalline CdSe nanobelt/2D PbI 2 flake hybrid heterojunction on a cost-effective flexible polyimide tape-based substrate.…”
