Fabrication and Characterization of Percolating Nanocluster Devices

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...

Physical simulation, fabrication and characterization of Wide bandgap semiconductor devices

Fabrication and Characterization of Organic Light Emitting Devices

By using Indium tin oxide (ITO) as anode material and NPB and Alq3 as hole transport layer(HTL) and electron transport layer(ETL) respectively, a Organic Light Emitting Device (OLED) with emitted wavelength of (525 ± 20) nm is produced. Aluminium (Al) is used as a cathode. The calculated emission energy is 2.37 ± 0.12 eV compared to theoretically 2.8 eV from the band gap in Alq3. This shifting ...

Tunable and Broadband Nanostructured Photonic Devices: Fabrication and Characterization

The main topic of this thesis is the fabrication and characterization of structures smaller than the wavelength of light, for operation in the visible or near infrared spectral range. In the first part of this thesis, the fabrication of periodic structures in one and two dimensions with an interference photolithography technique is described in detail. The structure periodicities that have been...

Fabrication and nanostructural characterization of TiO2 nanorods

TiO2 nanorods are synthesized by a thermal corrosion. In present work, synthesis of TiO2 nanorods in anatase, rutile and Ti8O15 phases, by using the sol-gel method and alkaline corrosion are reported. The morphologies and crystal structures of TiO2 nanorods are characterized by use of field emission scanning electron microscopy, atomic force microscopy and X-ray diffractometer techniques. The o...
