Development of indium tin oxide (ITO) nanoparticle incorporated transparent conductive oxide thin films
Yavaş, Hakan; Durucan, Caner; Department of Metallurgical and Materials Engineering (2012)
Indium tin oxide (ITO) thin films have been used as transparent electrodes in many technological applications such as display panels, solar cells, touch screens and electrochromic devices. Commercial grade ITO thin films are usually deposited by sputtering. Solution-based coating methods, such as sol-gel however, can be simple and economic alternative method for obtaining oxide films and also ITO. In this thesis, “ITO sols” and “ITO nanoparticle-incorporated hybrid ITO coating sols” were prepared using indi...
Investigation of the electromagnetic properties of single walled carbon nanotube thin films
Küçükyıldız, Şeyda; Dericioğlu, Arcan Fehmi; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2013)
The work presented in this thesis can be divided in two parts. First part discusses the dispersion and deposition routes of single walled carbon nanotube (SWNT) thin films. Two different types of SWNTs and several dispersing agents were examined to achieve a homogeneous SWNT solution. A tip-sonicator and an ultrasonic bath was compared and it has been found that tip-sonicator increases the efficiency of SWNT dispersions. Vacuum filtration and spray coating techniques were utilized for the deposition of SWNT...
Investigation of perfluoropentacene thin films on substrates with different chemical structures
Yavuz, Adem; Danışman, M. Fatih.; Department of Micro and Nanotechnology (2020)
Due to their promising properties in electronic device applications, organic semiconductors (OSs) are being studied heavily. In this study, we aimed to investigate the structural properties of PerFluoroPentacene (PFP) thin films on flat and vicinal Au(111), and Ag(111) surfaces grown by the Supersonic Beam Deposition(SMBD) technique as a function of film thickness, metal surface step density, the effect of chemical and electronic properties of substrate, molecular flux (deposition rate), and energy during f...
Investigation of structural and optical characteristics of thermally evaporated Ga2Se3 thin films
Isik, M.; Hasanlı, Nızamı (2020-09-01)
Ga2Se3 thin films were prepared by thermal evaporation technique and structural, optical characteristics of the deposited thin films were investigated in the present study. X-ray diffraction pattern of the thin film exhibited one intensive and sharp peak associated with (111) plane of cubic crystalline structure of the compound. Energy dispersive spectroscopic analyses pointed out the atomic compositional ratio of the constituent elements as consistent with chemical formula of Ga2Se3. The optical characteri...
Investigation of optical parameters of thermally evaporated ZnSe thin films
Gullu, H. H.; Coşkun, Emre; Parlak, Mehmet (2015-04-29)
In this work, zinc selenide (ZnSe) thin films were deposited by thermal evaporation method using pure elemental (Zn and Se) sources. The physical properties of the films have been investigated in terms of the structural and optical characterizations depending on the post-annealing process under nitrogen atmosphere in the temperature between 300 and 500 degrees C for 30 min. The structural and compositional analyses were carried out by means of X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy...
