Fabrication of Si nanocrystals in an amorphous SiC matrix by magnetron sputtering
Gencer Imer, A.; Yıldız, İlker; Turan, Raşit (Elsevier BV, 2010-7)
Si nanocrystals embedded in a wide bandgap material have been of interest for various electronic devices, including third-generation solar cells with efficiency values exceeding theoretical limits. In this work, Si-rich amorphous SiC layers with different Si contents were fabricated by the RF magnetron sputtering deposition technique. Si nanocrystal formation was induced by a high-temperature annealing process in a series of samples with different Si contents controlled by the DC power applied to the Si tar...
Fabrication of various metal nanostructures with hole mask colloidal lithography
Öztürk, İbrahim Murat; Bek, Alpan; Department of Physics (2014)
In this work, a novel surface nanostructuring technique called hole mask colloidal lithography (HMCL) is investigated and utilized to fabricate large area metal nanostructures with several geometries with photoresist over exposure and over develop as the undercutting method. Some extends of this method has been examined with constant angled deposition of dimer structures. HMCL takes advantage of directional nature of thermal evaporation method for metal deposition through the nanoscale holes that are placed...
Fabrication of D-A-D type conducting polymer, carbon nanotubes and silica nanoparticle-based laccase biosensor for catechol detection
Deniz, Sıddıka Aybüke; Göker, Seza; Toppare, Levent Kamil; Soylemez, Saniye (2022-08-01)
© 2022 The Royal Society of Chemistry.Herein, the biosensor design incorporates triple key materials based on amino-functionalized silica nanoparticles (SiNPs), both thieno[3,2-b]thiophene and 2,1,3-benzoselenadiazole groups containing a D-A-D type conducting polymer, and multiwalled carbon nanotubes (MWCNTs). First, the D-A-D type conducting polymer (PBSeThTh) containing thieno[3,2-b]thiophene and 2,1,3-benzoselenadiazole groups was synthesized and characterized in detail. Second, the biosensor surface was...
Fabrication of alumina/polyimide multi-layered material by sputtering and vapor deposition polymerization
Naganuma, Tamaki; Kakisawa, Hideki; Dericioğlu, Arcan Fehmi; Kagawa, Yutaka (2006-08-01)
The alumina/polyimide multi-layers were fabricated by dry process using sputtering and vapor deposition polymerization. The alumina layer and polyamic acid layer as a polyimide precursor were coated on a Si substrate at room temperature. The layered structure was prepared under the continuous and discontinuous depositions; the former was to evaporate continuously under vacuum, while the latter was to expose in air after each layering process and to form the next layer under vacuum. After alternating deposit...
Fabrication of helical polymeric hollow fiber membranes and characterization of their fouling behaviours
Yücel, Hazal; Çulfaz Emecen, Pınar Zeynep; Department of Chemical Engineering (2018)
Membranes are used in many separation processes such as gas separation, microfiltration, ultrafiltration and hemodialysis. Hollow fiber membranes are advantageous since they have a high surface area per volume and are easily backwashed which is an advantage for fouling removal. The most important factors that affect the performance of filtration membranes are concentration polarization and fouling. They increase operational cost and reduce membrane lifetime and permeate flux. One approach that can reduce co...
