چکیده
Recently, black phosphorus (BP), an emerging layered two-dimensional (2D) material, has aroused much research interest. Distinguished from most of other 2D materials, BP is always a direct bandgap semiconductor regardless the thickness, with ranging 0.3 eV (bulk) to 1.7 (monolayer), which just fill gap in between graphene and transition metal dichalcogenides (TMDCs) this frequency range. Besides, exhibits many intriguing properties, such as high carrier mobility, highly tunable anisotropic physical render another star material following TMDCs. In review, we mainly focus on advances optical properties BP, content covering intrinsic external perturbation effects properties. Regarding introduce layer-dependent absorption interband transitions, exciton binding energy absorption, visible-to-infrared photoluminescence, stability photoluminescence. As for in-plane uniaxial biaxial strain effects, gate-induced quantum confined Franz-Keldysh effect Burstein-Moss effect. And finally give brief summary outlook, pointing out some several interesting important issues need further studying urgently hyperbolic plasmons, intersubband heterostructures twist angle moiré superlattice so on. This review gives overview expected arouse interest BP.

Amorphous two-dimensional black phosphorus with exceptional photocarrier transport properties
Recently, two-dimensional materials have been extensively studied. Due to the reduced dielectric screening and confinement of electrons in two dimensions, these materials show dramatically different electronic and optical properties from their bulk counterparts. So far, studies on twodimensional materials have mainly focused on crystalline materials. Here we report studies of atomically thin am...

متن کاملTwo-dimensional magnetotransport in a black phosphorus naked quantum well
Black phosphorus (bP) is the second known elemental allotrope with a layered crystal structure that can be mechanically exfoliated to atomic layer thickness. Unlike metallic graphite and semi-metallic graphene, bP is a semiconductor in both bulk and few-layer form. Here we fabricate bP-naked quantum wells in a back-gated field effect transistor geometry with bP thicknesses ranging from 6±1 nm t...
