We investigated the potential, applicability, and advantages of DUV scatterometry including DUV ellipsometry for the dimensional characterisation of the absorber structures on EUV photomasks. By means of numerical investigations on the basis of rigorous diffraction calculations we demonstrate the sensitivity of DUV sc…
Abstract Using the local spin‐density approximation (LSDA) and the (non self‐consistent) GWapproach, the (quasiparticle) band structure is calculated forMnTe in zinc‐blende geometry. Different parameters characterizing the electronic structure are computed for an antiferromagnetic and the ferromagnetic phase and compa…
The preferred oriented texture Ge2Sb2Te5 (GST) thin film was prepared on SiO2∕Si(001) and TiN(60nm)∕Si(001) substrates. With the modulated layers of each constituent materials, the stoichiometry of thin film was controlled. Through cross section transmission electron microscope analysis and the x-ray diffraction (XRD)…
The rigorous integral equation method (viz MIM) in which the border structure is represented by a multilayer 1-D grating working at small wavelength-to-period ratios is used for taking into account electromagnetic scattering from different-types of nano-irregularities, such as periodical, random, self-organized, and t…
The effects of substrate bias on two types of oxide composite perpendicular recording media CoCrPt–SiO2 and FePt–MgO were investigated. The use of substrate bias greatly modified the thin film microstructure and resulted in the enhanced grain decoupling in the films. The growth characteristics due to preferential resp…
Abstract The potential application of Surface Plasmon Resonance (SPR) spectroscopy in evaluating the thickness and volume fraction of adsorbed macromolecular layers is discussed in this work. The sensitivity of SPR spectroscopy to different layer concentration and to the layer extension normal to the surface (thicknes…
Abstract It was found that reactions of 2‐Me 3 Si‐R‐substituted (Si–C sp or Si–C ) imidazolidine‐1,3‐diols with PbO 2 in MeOH are cascade reactions, which involve the oxidation of imidazolidine‐1,3‐diols into nitronyl nitroxide (NN–R–SiMe 3 ) and further elimination of the Me 3 Si group to give NN–R–H. The efficiency…
The relaxation dynamics in amorphous polystyrene and blends with polyethylene oxide (PEO) has been investigated by low-frequency anelastic spectroscopy. The dissipation spectra exhibit two relaxation peaks, corresponding to the α relaxation and the α′ (liquid-liquid) transition, respectively. The origin of the liquid-…
The overlay control budget for the 32nm technology node will be 5.7nm according to the ITRS. The overlay metrology budget is typically 1/10 of the overlay control budget resulting in overlay metrology total measurement uncertainty (TMU) requirements of 0.57nm for the most challenging use cases of the 32nm node. The cu…
Abstract The synthesis, thermal, and gas transport properties of poly(benzophenone isophthalamide), DBF/ISO, poly(benzophenone‐5‐ tert ‐butylisophthalamide), DBF/TERT, homopolymers, and their copolyamides with different DBF/TERT ratios are reported. The results indicate that the glass transition temperatures of the co…
We have studied the dynamics of a trimer of vinyl acetate (3VAc) using broadband dielectric spectroscopy over a wide temperature range to cover its primary and secondary relaxations. The dielectric spectra for the primary process over the entire temperature range have been described in terms of the Kohlraush-Williams-…
Ab initio embedded-cluster calculations have been performed for the CeO2(110) surface using temperature induced structures from molecular dynamics (MD) snapshots. As a first step towards understanding how temperature induced distortions of the surface structure influence the surface oxygen reactivity, the energy cost…
An analytical approach is proposed for simultaneously determining the inelastic mean-free path (IMFP), the surface excitation parameter (SEP), and the differential SEP (DSEP) in absolute units from an absolute reflection electron energy loss spectroscopy (REELS) spectrum under the assumption that the normalized differ…
The inhibition of corrosion of steel by two P-containing compounds, sodium methyldodecyl phosphonate and sodium methyl (11-smethacryloyloxyundecyl) phosphonate, in hydrochloric acid has been investigated at various temperatures using electrochemical techniques (impedance spectroscopy (EIS), potentiodynamic polarizatio…
Nitrogen oxides (NOx) are major air pollutants as they have adverse effects on health and the environment. Various types of combustion equipment, including biosolids incinerators, are the sources of NOx emissions in the atmosphere. Various source control measures in the form of the use of low NOx burners and burner st…
Axial strain is introduced into individual single wall carbon nanotubes (SWCNTs) suspended from a trench-containing Si∕SiO2 substrate by employing the van der Waals interaction between the SWCNT and the substrate. Resonance Raman spectroscopy is used to characterize the strain, and up to 3% axial strain is observed. I…
The authors demonstrate the production of amorphous fluorinated carbon (a-C:F) thin film with adjustable wetting properties, inducing variable liquid crystal (LC) pretilt angles. To control the surface wetting properties, they apply a dual radio frequency magnetron system with a controlled power ratio of targets. In t…
Presently existing THz electromagnetic metamaterials were mostly produced as planar single layer structures, either deposited on a substrate or embedded in a polymer matrix, and patterned by a primary pattern generator such as an electron beam writer or a laser writer. Some attempts to produce more voluminous structur…
Abstract Scanning electron microscopy (SEM) study of the morphologic change of high‐density polyethylene (HDPE) surface grafted with glycidyl methacrylate (GMA) was reported. Radiation‐induced grafting of GMA onto HDPE was carried out in acetone and dichloromethane solution, respectively. The effects of irradiation do…
Magneto-optical techniques in reflection geometry turn out to be a very efficient tool to study the surface magnetism due to their sensitivity to magnetic and chemical variations across the sample depth. The existence of a surface layer of about one to five unit cells with strongly depressed magnetic properties, when…
