Pulsed periodic photothermal radiometry (PPTR) allows the investigation of multilayered samples with layer thicknesses a few hundred nanometers over duration nanoseconds. The link between theoretical calculations and experimentation is made using Bayesian approach based on Metropolis–Hastings algorithm. accuracy PPTR method requires precise calibration to provide an accurate proper emission mea...

In this work the suitability of some Tibased coatings as coating for blood-contacting implants is analyzed. Layers of pure Ti, Ti nitride, Ti oxynitrides (TiN1-xOx with x = 0.25, 0.50, and 0.75) and Ti oxides were deposited from a plasma produced by cathodic arc evaporation under addition of N2 and/or O2. The oxynitrides are crystalline with the fcc structure of TiN up to x = 0.25. For x = 0.5 ...

Perovskite solar cells (PSCs) have attracted tremendous attentions due to its high performance and rapid efficiency promotion. Compact layer plays a crucial role in transferring electrons and blocking charge recombination between the perovskite layer and fluorine-doped tin oxide (FTO) in PSCs. In this study, compact TiO2 layers were synthesized by spin-coating method with three different titani...

Electrode-to-cell/tissue interfaces with high biocompatibility, low impedance, and long-term chemical mechanical stability are of paramount importance in numerous biological biomedical applications. For meticulous monitoring parameters, there is a rapidly growing interest sensing at subcellular levels radically improved spatiotemporal resolution, which necessitates ultra-miniaturized electrodes...

Titanium dioxide (TiO2) nanoparticles were modified onto fluorine-doped tin oxide (FTO) via dip-coating technique with different nanoparticle sizes, lifting speeds, precursor concentrations, and dipping numbers. Electrodeposition-based electrochromic device with reversible three-state optical transformation (transparent, mirror, and black) was fabricated subsequently by sandwiching a suitable a...

Nanometer-scale patterning of TiN films grown on SiO2 /Si(001) has been demonstrated using the local electric-field-induced oxidation process with a conductive-probe atomic force microscope. The chemical composition of the modified TiN region was determined by micro-Auger electron spectroscopy and was found to consist of Ti, some trace amount of N, and O, suggesting the formation of titanium ox...

As semiconductor devices become miniaturized, the importance of molecular-level understanding fabrication processes is growing. Titanium nitride (TiN) an important material utilized in various architectural components requiring precise control over size and shape. A reported process for atomic layer etching (ALE) TiN involves surface oxidation into titanium oxide (TiO2) selective oxidized remov...

Thin films composed of titanium nitride doped with silver were deposited by DC reactive sputtering, with Ag contents varying between 0 and 50 at.%. The as-deposited samples were subjected to vacuum annealing treatments, with a range of temperatures varying from 200 to 500°C, in order to study the morphological and structural changes that may occur. The as-deposited samples showed three main zon...

Titanium nitride (TiN) has emerged as one of the most promising refractory materials for plasmonic and photonic applications at high temperatures due to its prominent optical properties along with mechanical thermal stability. From a temperature standpoint, TiN is substitution Au Ag in visible near-infrared wavelength range, potential including thermophotovoltaics, thermoplasmonics, hot-electro...
