Depth profiling of thin plasma-polymerized amine films using GDOES in an Ar-O2 plasma

چکیده
Thin polymer films were deposited on polished stainless-steel samples by PECVD from a cyclopropylamine precursor and characterized X-ray photoelectron spectroscopy, secondary-ion mass spectrometry glow-discharge optical emission spectroscopy (GDOES) depth profiling. These profiles exhibited reasonable agreement. The GDOES involved the erosion of in plasma sustained an asymmetric RF capacitively coupled discharge using both Ar Ar-O2 gases. application pure caused unwanted effects, such as broadening polymer-film/substrate interface, which suppressed when mixture with oxygen. Another benefit oxygen was significant increase etching rate factor about 15 compared to argon. mechanisms profiling gases elaborated some detail, taking into account parameters typical for asymmetric, small volume. main Ar/O2 respect XPS SIMS is increased sputtering films. Comparing Ar, benefits are higher better resolution at polymer/substrate interface.

Organic–inorganic hybrid co-polymer thin films were deposited on silicon(100) substrates under the several ratio of TEOS (tetraethoxysilane) against cyclohexene by plasma enhanced chemical vapour deposition (PECVD) method. Toluene and TEOS were utilized as organic and inorganic precursors each, and hydrogen and argon were also used as a bubbler and carrier gases, respectively. In order to compa...
متن کاملGrowth kinetics of plasma-polymerized films
The growth kinetics of polymer thin films prepared by plasma-based deposition method were explored using atomic force microscopy. The growth behavior of the first layer of the polythiophene somewhat differs from that of the other layers because the first layer is directly deposited on the substrate, whereas the other layers are deposited on the polymer itself. After the deposition of the first ...

The plasma polymerization of NIPAAM and titanium isopropoxide monomers into responsive ultrathin films with responsive optical properties using plasma enhanced chemical vapor deposition is reported. The composite ultrathin films possess a large window for potential changes in their refractive index from 1.60 to 1.95. We demonstrated that these polymer films exhibit fast (transition time below 2...

The complex direct current (DC) electrical conduction mechanism in plasma polymerized pyrrole (PPPy) thin films has been discussed in this article. PPPy thin films of different thicknesses were deposited at room temperature onto glass substrates by using a parallel plate capacitively coupled glow discharge reactor and their properties were studied in detail. In the study of DC conduction proper...
