Ultrahigh Power Factor of Sputtered Nanocrystalline N‐Type Bi2Te3 Thin Film via Vacancy Defect Modulation and Ti Additives

Advanced Science
Magnetron‐sputtered thermoelectric thin films have the potential for reproducibility and scalability. However, lattice mismatch during sputtering can lead to increased defects in the epitaxial layer, which poses a significant challenge to improving their

Broadband Interferenceless Perfect Absorption in Hexagonal Boron Nitride and Lithium Fluoride Hyperbolic Metamaterial

Advanced Photonics Research, EarlyView.
The images (a) and (b) illustrate a composite metamaterial with anisotropic permittivity. When incident light, polarized in transverse magnetic or transverse electric modes, enters the structure, the reflectance spectra in (c) and (d) show low reflection and high absorption over a wide range of incidence angles. This behavior has potential applications

Design of Waveguide NbN‐Based Superconductor–Insulator–Superconductor Mixer for 650 GHz

Advanced Photonics Research, EarlyView.
This research work focuses on a waveguide NbN‐based superconductor–insulator–superconductor mixer operating at 650 GHz. The signal coupling circuit is designed using a waveguide‐microstrip coupling structure, and the return loss obtained is lower than −16 dB. For the mixing circuit, its return loss is less than −7.5 dB, and the return loss reduces with

Frequency‐Dependent Demethylation of Cancer DNAs by High‐Power Terahertz Radiation

Advanced Photonics Research, EarlyView.
Effective demethylation of cancer DNA is successfully demonstrated by resonant irradiation with high‐power terahertz (THz) waves at the 10 mW level, combined with metamaterial‐based THz filters. The dependence of spectral filtering on demethylation indicates that the resonant frequency of 1.6 THz of cancer DNAs plays a crucial role in reducing the ...

Plasmonic Hot Spots on Topological Insulator Nanotips for Enhancing Light Interaction with MoS2 Atomic Monolayer [invited]

Advanced Photonics Research, EarlyView.
A pair of Sb2Te3 topological insulator (TI) nanotips is fabricated by using the focused ion beam lithography to demonstrate the plasmonic hot spot effect at the visible range. The strong enhancement of electric field can be generated on the TI nanotips due to the plasmonic effect, giving rise to the obvious improvement of photoluminescence emission ...
