Abstract We demonstrate experimentally that Tamm plasmons in the near infrared can be supported by a dielectric mirror interfaced with metasurface, discontinuous thin metal film periodically patterned on sub-wavelength scale. More crucially, not only do survive nanopatterning of but they also become sensitive to external perturbations as result. In particular, depositing nematic liquid crystal outer side we were able red shift spectral position plasmon 35 nm, while electrical switching...

We show here that intrinsic hydrophobicity of HfO2 thin films can be easily tuned by the variation film thickness. used reactive high-power impulse magnetron sputtering for preparation high-quality with smooth topography and well-controlled Results a strong dependence wetting properties on thickness in range 50–250 nm due to dominance electrostatic Lifshitz-van der Waals component surface free energy. have found water droplet contact angle ranging from ≈120° 50 ≈100° 2300 nm.

The laser damage resistance of an optical element in high power systems depends significantly on the surface quality substrate. In this experiment, commercially polished fused silica substrates were etched argon plasma generated by a RF source and their roughness, flatness properties investigated. This method can be applied vacuum chamber prior to deposition multilayer coatings without breaking vacuum. It was shown that etching 355 nm, radiation could improved more than 8 times. However, it...

Reactive high-power impulse magnetron sputtering discharge has been studied experimentally combining optical emission, absorption, and laser-based diagnostic techniques. The quantification of the atomic ground state densities is performed using emission spectroscopy. Hysteresis behavior as a function molecular oxygen flow fraction in Ar-O2 mixture observed for numerous parameters, such density O atoms, sputtered atoms ions, Ar metastables, etc. obtained number are found to be full agreement...

We report on the experimental observation of a Tamm plasmon state in near-IR region characterized by an anomalously high energy level located upper half photonic band gap. Such "blue" was demonstrated at interface between conventional, completely periodic Bragg reflector and nanostructured nonresonant thin gold grating. study effect grating period characteristics anomalous show that anomaly results from nontrivial topology nanograting's optical near field, which cannot be captured effective...

Scandium oxide (Sc 2 O 3 ) films are deposited by reactive magnetron sputtering. The effects of annealing on the structure, as well optical, mechanical, and electrical properties investigated. detailed investigation mechanical high load indentation resistance in combination with optical is done. It noted that after at 300 °C, extinction coefficient refractive index slightly decreases. reported before annealing, Sc cubic phase remains very hard (19 GPa) resistant to (up 1N) test. Moreover,...

Recently, we reported novel set data for electrical properties...

High-power impulse magnetron sputtering with a pulsed O2 flow control was used for reactive deposition of densified stoichiometric ZrO2 films gradient ZrOx interlayers onto floating Si and steel substrates at low substrate temperatures (less than 150 °C).
