“…Perovskite oxide superlattices continue to be of both fundamental and technological interest due to their wide variety of functional properties as well as the progress in atomic scale precision growth techniques that enable their realization [1][2][3][4]. There is particular interest in systems in which the layering gives rise to distinctive functional properties, including enhancement of properties such as the piezoelectric response over those of either constituent [5].…”

In the first-principles bulk-layer model the superlattice structure and polarization are determined by first-principles computation of the bulk responses of the constituents to the electrical and mechanical boundary conditions in an insulating superlattice. In this work the model is extended to predict functional properties, specifically dielectric permittivity and piezoelectric response. A detailed comparison between the bulk-layer model and full first-principles calculations for three sets of perovskite oxide superlattices, PbTiO3/BaTiO3, BaTiO3/SrTiO3 and PbTiO3/SrTiO3, is presented. The bulk-layer model is shown to give an excellent first approximation to these important functional properties, and to allow for the identification and investigation of additional physics, including interface reconstruction and finite size effects. Technical issues in the generation of the necessary data for constituent compounds are addressed. These results form the foundation for a powerful data-driven method to facilitate discovery and design of superlattice systems with enhanced and tunable polarization, dielectric permittivity, and piezoelectric response.

“…At present, there are two main fabrication methods, one is called the topdown method, and the other is called the bottom-up method [49][50][51]. The former includes mechanical exfoliation (ME) [52][53][54], liquid phase exfoliation (LPE) [27,43,55], electrochemical exfoliation [51,56], thermal annealing [57], plasma thinning [58,59] and sonochemical exfoliation method [60][61][62][63]; the latter includes chemical vapor deposition (CVD), pulsed laser deposition [64][65][66][67], hydrothermal method [66], van der Waals epitaxy [68,69] and magnetron sputtering deposition (MSD) [48,70]. We will briefly introduce three common preparation methods: ME, LPE and CVD.…”

The tunable bandgap from 0.3 eV to 2 eV of black phosphorus (BP) makes it to fill the gap in graphene. When studying the properties of BP more comprehensive, scientists have discovered that many two-dimensional materials, such as tellurene, antimonene, bismuthene, indium selenide and tin sulfide, have similar structures and properties to black phosphorus thus called black phosphorus analogs. In this review, we briefly introduce preparation methods of black phosphorus and its analogs, with emphasis on the method of mechanical exfoliation (ME), liquid phase exfoliation (LPE) and chemical vapor deposition (CVD). And their characterization and properties according to their classification of single-element materials and multi-element materials are described. We focus on the performance of passively mode-locked fiber lasers using BP and its analogs as saturable absorbers (SA) and demonstrated this part through classification of working wavelength. Finally, we introduce the application of BP and its analogs, and discuss their future research prospects.

“…As one of the most fascinating electronic ceramic materials, strontium titanate (SrTiO3) has attracted much attention because of its high static dielectric constant [1,2], large electron effective mass and large Seebeck coefficient [3], which has led to promising technological applications [4][5][6][7]. Due to its high efficiency, stability and strong reducing ability in the photocatalytic field, SrTiO3 can also be employed as a feasible photocatalyst [8][9][10][11][12][13].…”

The magnetic and electronic properties of strontium titanate with different carbon dopant configurations are explored using first-principles calculations with a generalized gradient approximation (GGA) and the GGA+U approach. Our results show that the structural stability, electronic properties and magnetic properties of C-doped SrTiO3 strongly depend on the distance between carbon dopants. In both GGA and GGA+U calculations, the doping structure is mostly stable with a nonmagnetic feature when the carbon dopants are nearest neighbors, which can be ascribed to the formation of a C
