In order to elucidate their potential applications in various technological domains, this work explores the electronic and optical characteristics of two distinct phosphorene/2D-TiO2 van der Waals heterostructures, namely, the Blue P/2D-TiO2 and Black P/2D-TiO2 heterostructures, with the aid of dislocation engineering. The charge transfer, energy alignments, and charge carrier mobility were calculated by the first-principles. The alignment of energy levels and the charge transfer phenomenon reveal the potential of the Blue P/TiO2 heterostructure for photocatalytic water decomposition and CO2 reduction, which can be fine-tuned through mechanical strain, making it a promising candidate for optoelectronic devices. In addition, the Black P/TiO2 heterostructure exhibits unique semimetallic characteristics, featuring an occurrence of conduction band bottom and valence band top coincidentally intersecting. With remarkably high charge carrier mobility up to 4.01 × 103 cm2 V–1 s–1, the intriguing property indicates its potential for application in electronic devices.

Based on the first-principles calculation, the electronic and optical properties of the graphene/MoS2 heterostructure at different twisting angles are studied. The interface contact type changes from N-Schottky contact to Ohmic contact with the interlayer twisting angle of 40.90°, which is accompanied by the interfacial charge transfer from graphene to MoS2, and the increase of the contribution of Mo-dxy, Mo-dx2-y2 orbitals in the conduction band and S-pz, Mo-s, Mo-pz and Mo-dz2 orbitals in the valence band. Interestingly, the absorption coefficient, reflectivity and refractive index are improved in the infrared region when the twisting angle is 40.90°. In the visible light range, the absorption coefficient increases, while the refractive index decreases, and the reflectivity at 2.8 eV increases. In the ultraviolet region, the absorption coefficient reaches 1.2×106 cm-1 at 11.6 eV with a twisting angle of 30°. The results provide an effective way to apply materials in the photoelectric field.
