Growth of single-crystal black phosphorus and its alloy films through sustained feedstock release

Renaissance of elemental phosphorus materials: properties, synthesis, and applications in sustainable energy and environment

“…To resolve this issue, the group has recently implemented a sustained feedstock release strategy for synthesizing single-crystal black-P thin films, focusing on promoting the lateral growth mode at low nucleation rates. 246…”

“…The as-grown black-P single-crystal film exhibits outstanding single crystallinity, as evidenced by the full-width at half-maximum of the (040) reflection rocking curve, measured at ∼0.08° using high-resolution XRD. 246 Furthermore, the film has a remarkable carrier mobility of around 6500 cm 2 V −1 s −1 at low temperature. This study marks the first observation of Shubnikov-de Haas oscillations in directly grown black-P films.…”

Suspended Black Arsenic Nanoribbons with Anisotropic Elastic Properties for Nanomechanical Devices

“…Anisotropic two-dimensional (2D) layered nanomaterials have emerged in the recent years and have attracted extensive attention due to their unique atomic structures and distinguished physical properties, which intrinsically endow the orientation-dependent transport behaviors and numerous potential applications in nanodevices and nanoelectronics. − Intriguingly, anisotropic 2D nanomaterials generally possess lattice structures with very low symmetry, much different from the isotropic 2D materials, including the well-studied 6-fold graphene and transitional metal dichalcogenides . As a new degree of freedom, anisotropy in specific 2D materials, such as the orthorhombic black phosphorus (b-P, space group cmce), renders them two principal lattice axes in the basal plane, that is, the orthogonal zigzag (ZZ) and armchair (AC) directions. − Till now, many investigations have been performed to explore the anisotropic electrical, phonon vibrational, and thermal properties of 2D b-P. − For instance, the anisotropic ratio of thermal conductivity of b-P is determined to be ∼1.8 in the experiment, mainly attributed to the superior phonon velocity and scattering process along the ZZ direction …”
