Black phosphorus (BP) as a rising star among 2D materials has attracted attention for wide range of applications due to its fascinating properties. The key point the real application phosphorene depends on exfoliation technique produce high-quality nanosheets. In recent years, tremendous efforts have been made in preparation and energy storage phosphorene-based hybrid electrodes. Herein, state-...

Tunable and ultrasensitive surface plasmon resonance (SPR) sensors are highly desirable for monitoring stress hormones such as cortisol, a steroid hormone formed in the human body’s adrenal glands. This paper describes detection of cortisol using bimetallic SPR sensor based on anisotropic two-dimensional material, i.e., phosphorene. Thicknesses bi-metal layers, copper (Cu) nickel (Ni), optimize...

We report the tailoring of the electronic structures of various structural phases of phosphorene (α-P, β-P, γ-P and δ-P) based homo- and hetero-bilayers through in-plane mechanical strains, vertical pressure and transverse electric field by employing density functional theory. In-plane biaxial strains have considerably modified the electronic bandgap of both homo- and hetero-bilayers while vert...

Black phosphorus (BP), a new two-dimensional material, has been the focus of scientists' attention. BP nanotubes have potential in the field of optoelectronics due to their low-dimensional effects. In this work, the bending strain energy, electronic structure, and optical properties of BP nanotubes were investigated by using the first-principles method based on density functional theory. The re...
