“…Figure 4 shows the dispersion curves along the symmetry lines in the Brillouin zone, where negative values express the imaginary phonon frequency. The positive frequency values indicate the dynamical stability structures [38,47], while the negative ones indicate dynamical instability [48]. Figure 4(a) depicts the phonon band of SiC for square and honeycomb structures.…”

This work presents a study of novel two-dimensional (2D) square-structured diatomic group-IV materials through density functional theory calculations. Our optimized structures have a planar structure. Moreover, we evaluate the structural stabilities and electronic properties of six square-structured 2D-diatomic XY (X, Y = C, Si, Ge, Sn) materials. In comparison, we also evaluate the honeycomb structure of those materials. The Birch-Murnaghan equation of states (BM-EOS) curves and cohesive energy evaluations indicate that the square-structured SnGe and SnSi materials are highly stable. Interestingly, most of the square-structured materials are dynamically stable based on phonon dispersion evaluation, except SnC material. More importantly, most of the square-structured materials have a narrower bandgap energy which implies better electronic properties. In particular, square-structured SnGe shows an ultra-wide bandgap of 4.02 eV which is prospective for future electronics. Furthermore, we believe that the stable square structures will be observed in the experiment and will be beneficial for future device applications.

“…At present, some metal ions such as Sn 2+ , Mn 2+ , Tb 3+ , Cu 2+ , In 3+, and Cd 2+ have been used to replace Pb 2+ for constructing lead-free perovskite materials and devices. [174][175][176][177][178][179][180][181][182][183][184] Regrettably, the brightness and EQE of lead-free perovskite devices still lag far behind those of Pb-based devices. In addition, the devices are not well studied in terms of energy level matching and interfacial interaction.…”

Perovskite, as a star fluorescent material, has the characteristics of adjustable luminescence peak, high color purity, high photoluminescence quantum yield, and low cost, showing significant potential in the photoelectric field. Among the RGB colors for display devices, green is the most sensitive color for human eyes, and green perovskite light‐emitting diodes (GPeLEDs) have aroused much interest in recent years. In this work, the research history of GPeLEDs is reviewed, the perovskites of different dimensions are introduced, and the common synthesis methods of perovskites are discussed. Besides, the strategies to improve the stability and luminous efficiency of GPeLEDs are summarized, including component engineering, phase engineering, ligand engineering, additive engineering, interface engineering, and optical coupling structure strategy. Finally, the development state of GPeLEDs is summarized and prospected. This work is expected to stimulate more unprecedented achievements derived from GPeLEDs, thus promoting their practical applications in future ultra‐high‐definition displays.
