Black phosphorus is an allotrope of phosphorous that, like graphite, can be exfoliated to create two-dimensional materials. Here, the authors use Raman spectroscopy and density functional theory calculations to investigate the anomalous behaviour of

Epsilon near-zero photonics and surface polariton nanophotonics have become major fields within optics, leading to unusual and enhanced light-matter interaction. Specific dielectric responses are required in both cases, which can be achieved, e.g., v

Publikováno v: Frontiers in Optics / Laser Science.

We present a comparison of three laser setups for the photothermal production of reduced graphene oxide thin films on a nitrocellulose membrane. The lowest electrical resistance obtained was 800Ω, which is attractive for conductive applications.

Publikováno v: Conference on Lasers and Electro-Optics.

We present a pressure sensor using an optical frequency domain reflectometer and a simplified microstructured fiber. High sensitivity, ease of fabrication and distributed sensing makes the proposed configuration a promising technique for pressure sen
