Abstract Highly transparent lead‐free (1‐ x )K 0.5 Na NbO 3 – Sr(Zn 1/3 Nb 2/3 )O (KNN– SZN) ferroelectric ceramics have been synthesized via a conventional pressureless sintering method. All samples are optically clear, showing high transmittance in the visible and near‐infrared regions (~70% ~80% at mm of thickness, respectively). This exceptionally good is due to pseudo‐cubic phase structure as well dense fine‐grained microstructure. In addition, energy storage density 3.0 J/cm has...

Abstract Transparent, Sr(Al 0.5 Nb )O 3 ‐modified K Na NbO (KNN) ceramics were successfully fabricated by a solid‐state pressureless sintering method in this work. The obtained microstructure, transmittance, and electrical properties characterized detail. Our results indicated that the modification significantly limited grain growth behavior of KNN, resulting dense with submicron size (<0.5 μm) small pore size. Consequently, ceramic 0.96K ‐0.04Sr(Al composition showed superior...
Ferromagnetic (FM) two-dimensional (2D) transition metal dichalcogenides (TMDs) have potential applications in modern electronics and spintronics doping of TMDs with metals can enhance the magnetic characteristics. In this work, structural stability, electronic states, properties Mn-doped monolayer/bilayer MoS2 are studied systematically by first-principles calculations. Substitutional Mn dopants at Mo sites energetically favorable both monolayer bilayer under S-rich condition which is...
It is difficult to generate p–n junctions in atomically thin transition metal dichalcogenides (TMDs) because of the great challenge selective doping.
The interlayer distance and biaxial strain affect the electronic properties contact of graphene/MoS 2 heterostructures.
Abstract Transparent piezoelectric ceramic, as a lead‐free multifunctional is in dire need of development for future high‐tech industries. However, excellent piezoelectricity and high transmittance are usually hard to achieve simultaneously, mainly due the two mutual restricting factors (phase structure grain size). In this work, we report that can be obtained simultaneously K 0.5 Na NbO 3 ceramics via Sr(Sc Nb )O ( SSN ) modification. The superior performance comes from retain orthorhombic...
Electrical contacts are crucial to the high performances of electronic devices, and they become more prominent for popular two-dimensional (2D) semiconductors because commonly have contact resistances sensitive interfacial states.
The electrocatalytic nitrogen reduction reaction (NRR) is a promising technology for the synthesis of NH3 in an ambient environment. However, developing low-cost and high-efficiency electrocatalysts still remains long-standing challenge. In this work, density function theory (DFT) calculations are done to systematically investigate NRR catalytic activity transition metals (TM = Sc-Cu, Y-Ag, Hf-Au) supported on monolayer graphyne (GY). TM@GY Sc, V, Mn, Y, Tc, Os) with excellent performance...
