Graphene has gained the attention of scientific world due to its outstanding physical properties. The future demand of flexible electronics such as solar cells, light emitting diodes, photo-detectors and touch screen technology requires more exploration of graphene properties on flexible substrates. The most interesting application of graphene is in organic light emitting diodes (OLED) where efforts are in progress to replace brittle indium tin oxide (ITO) electrode with a flexible graphene electrode because ITO raw materials are becoming increasingly expensive, and its brittle nature makes it unsuitable for flexible devices. In this work, we grow graphene on Pt and Cu substrates using chemical vapour deposition (CVD) and transferred it to a polymer material (PVA) using lamination technique. We used hydrogen bubbling method for separating graphene from Pt and Cu catalyst to reuse the substrates many times. After successful transfer of graphene on polymer samples, we checked the resistivity values of the graphene sheet which varies with growth conditions. Furthermore, Raman, atomic force microscopy (AFM), I-V and Force-displacement measurements will be presented for these samples.

Single- and multi-walled carbon nanotubes for solar cell applications Obaidullah, Madina; Esat, Volkan; Sabah, Cumali (2018-08-20) Emerging nanotechnologies have revealed carbon nanotubes (CNTs) as one of the best materials with immense potential. Considering the outstanding physical, mechanical, electrochemical, thermal, and optoelectronic properties of CNTs, extensive studies have been reported assessing their applications in several disciplines. This paper presents a broad review of the studies in the literature that address the contribution of CNTs in terms of their applications as different parts of solar cells such as photoelectr...
Peeling of Chemical Vapour Deposition Graphene Grown on Platinum and Copper foils using Alkaline Solutions for Reuseable Substrates Karamat, Shumaıla; Sonusen, Selda; Çelik, Ümit; Uysallı, Yiğit; Oral, Ahmet (null; 2015-04-10) Graphene, the wonder material, has gained worldwide scientific attention since its experimental existence in 2004. Its sp-2 bonded carbon atoms are arranged in a two dimensional honeycomb lattice which exhibits high intrinsic carrier mobility, transparency, and tensile strength. Chemical vapour deposition (CVD) is the most opted technique because of its potential for large area graphene growth. During CVD growth at high temperatures, the surface of the metal catalyst becomes rough due to surface reconstruct...
Molecular dynamics investigation of Moire Patterns in double-layer graphene Sökmen, Gökçe; Toffoli, Hande; Toffoli, Daniele; Department of Micro and Nanotechnology (2012) Before Moire patterns are discovered in graphene, graphene was assumed to be found in only the rhombohedral form in nature. After transfer of graphene layer over another substrate was achieved by Andre Geim and Konstantin Novoselov, studies on graphene gained momentum. Following this, moire paterns were observed by scanning tunelling microscopy (STM) and high resolution transmision electron microscopy (HR-TEM). However, stability of these structures are still unknown. In this thesis, for the first time in l...
Microwave assisted sythesis of rare earth ions doped lanthanum orthoborate, their characterizations and investigations of luminescence properties Badan, Cansın; Yılmaz, Ayşen; Esentürk, Okan; Department of Chemistry (2012) Lanthanum orthoborate (LaBO3) has aroused interest of scientists for many decades because of their remarkable properties and potential applications. They provide favorable magnetic properties for various applications. Additionally, they possess high VUV transparency and exceptional optical damage when they compose with rare earth elements. This study comprises the synthesis of pure lanthanum orthoborate, europium, dysprosium and terbium doped lanthanum orthoborate by two methods with v three fuels, citric a...
Terahertz modulation using a bandpass filter combined with a Graphene Supercapacitor Takan, Taylan; Nebioglu, Mehmet A.; Kakenov, Nurbek; Balci, Osman; KOCABAŞ, COŞKUN; Altan, Hakan (2015-09-22) Graphene is proving to be an efficient medium for the control of mm-wave/THz radiation. Its electrical and dielectric properties allows it to be incorporated into various existing device architectures. One such application is in the modulation of the amplitude of the propagating THz radiation. Due to its electrical properties this interaction is typically broadband in nature. To make this frequency selective we propose the use of metamaterials or frequency selective surfaces. Generally, these structures per...
