We report the temperature dependent photoluminescence (PL) properties of monolayer
graphene–Au-nanoparticle–ZnO (GAZ) microwire hybrid structures. By comparing with the …

Owing to its narrow indirect bandgap, bulk bismuth telluride (Bi2Te3) exhibits exceptionally
low room‐temperature photoluminescence (PL). Consequently, it remains challenging to …

The Bi2Se3/ZnO heterostructure is a new combination of high-and low-band-gap
nanomaterials that can be implemented for optoelectronic devices. The influence of the …

A pressing challenge in engineering devices with topological insulators (TIs) is that electron
transport is dominated by the bulk conductance, and so dissipationless surface states …

Topological insulators with Dirac conducting surface state and insulating bulk state offer a
promising platform for plasmonics with a broad operating frequency range from ultraviolet …

The propagation of Dyakonov waves guided by the planar interface of a columnar thin film
and a topological insulator was investigated by numerically solving the associated canonical …
