Influence of selenization temperature on synthesis, morphology, and properties of nanostructured CoSe2 films

03.01.2015 | Jen‐Bin Shi, Po‐Feng Wu, Chia‐Tze Kao, Ming‐Way Lee, Chih‐Chieh Chan, Ping‐Chang Yang, Cheng‐Li Lin, Rui‐Yo Huang, Y ..., Crystal Research and Technology, 2015

Nanostructured cobalt selenide (CoSe2) thin films were deposited on a glass substrate using the selenization of Co films at different selenization temperatures (300 °C, 400 °C, and 500 °C) in a pure Se vapor for two hours. The morphology and structure of the as‐deposited films shows that the ...

Doped Polycrystalline Silicon Thin Films Deposited on Glass from Trichlorosilane**

02.01.2015 | Ariel G. Benvenuto, Román H. Buitrago, Javier A. Schmidt, Chemical Vapor Deposition, 2015

Atmospheric pressure (AP) thermal CVD is used to deposit thin poly‐Si films on glass substrates. Also produced are heterojunction solar cells carrying out the deposition on c‐Si wafers. A batch‐type hot‐wall reactor, employing SiHCl3 as a precursor, H2 as a carrier and reaction gas, BBr3 as a ...

Combination of temperature and saturated vapor annealing for phase separation of block copolymer

29.12.2014 | Jan Švanda, Oleksiy Lyutakov, Vladimíra Vosmanská, Václav Švorčík, Journal of Applied Polymer Science, 2014

ABSTRACT Phase separation of block copolymer films is a perspective technique for the creation of nanostructured templates. The phase separation can be induced by thermal or vapor solvent annealing. However, a standardized and reproducible technique of the phase separation is still missing, ...

Cooling dynamics of self‐assembled monolayer coating for integrated gold nanocrystals on a glass substrate

26.12.2014 | Kouhei Ichiyanagi, Hiroshi Sekiguchi, Tokushi Sato, Shunsuke Nozawa, Ayana Tomita, Manabu Hoshino, Shin‐ichi Adachi, ..., Journal of Synchrotron Radiation, 2014

Picosecond time‐resolved X‐ray diffraction has been used to study the nanoscale thermal transportation dynamics of bare gold nanocrystals and thiol‐based self‐assembled monolayer (SAM)‐coated integrated gold nanocrystals on a SiO2 glass substrate. A temporal lattice expansion of 0.30–0.33% was ...

Synthesis of polyisocyanurates by thermal rearrangement of polycyanurates

23.12.2014 | Kousuke Tsuchiya, Eisuke Goto, Yoshihito Ishida, Tomoya Higashihara, Atsushi Kameyama, Mitsuru Ueda, Journal of Polymer Science Part A: Polymer Chemistry, 2014

ABSTRACT Polyisocyanurates have been successfully prepared by the thermal rearrangement of polycyanurates, which were obtained from 2,4‐dichloro‐6‐methoxy‐1,3,5‐triazine and bisphenol monomers. The thermal rearrangement was carried out in the presence of a small amount of tetrabutylammonium ...

Glass Formation Processes in Mixed Inorganic/Organic Aerosol Particles

23.12.2014 | Hans P. Dette; Thomas Koop, Journal of Physical Chemistry A, 2014

Recent experiments suggest that organic aerosol particles may transform into a glassy state at room temperature under dry conditions. Information on glass forming processes in mixed inorganic/organic aerosol particles is sparse, however, because inorganic crystal nucleation is usually very likely ...

Dielectric Properties of Ultra‐Low Sintering Temperature Al2O3–BBSZ Glass Composite

22.12.2014 | Mei‐Yu Chen, Jari Juuti, Chi‐Shiung Hsi, Chih‐Ta Chia, Heli Jantunen, Journal of the American Ceramic Society, 2014

Ceramic composites of B2O3–Bi2O3–SiO2–ZnO (BBSZ) glass mixed with Al2O3 (10–50vol%) were sintered at 450°C, and their microstructural and dielectric properties investigated. Dense structures were obtained when the Al2O3 content was lower than 30vol%. Raman, XRD, and FESEM showed the existence ...
