Persistent electronic cloaking and Klein tunneling in multiple phosphorene junctions

| Physical Review B
Electronic cloaking of confined states is an exotic phenomenon in bilayer graphene and phosphorene owing to the chirality mismatch between electrons and holes in an electrostatic barrier. Anti-Klein tunneling or almost perfect reflection, another exotic phenomenon in bilayer graphene, is also the manifestation of the chirality mismatch between electrons and holes in an electrostatic barrier. Anti-Klein tunneling can be destroyed by the multiplication of electrostatic barriers.

Thermoelectric properties of gated phosphorene junctions

| Physical Review B
Abstract The reduced dimensions of nanostructures offer opportunities to control and improve the performance of thermoelectric devices based on two-dimensional materials. Here, we investigate theoretically the thermoelectric properties of gated phosphorene junctions (GPJs). We focus on the electronic contribution due to the possible ultralow phononic thermal conductivity in GPJs. The effects of nanostructuration, temperature, and phosphorene anisotropy are analyzed.
