Atomic layer deposition of III-nitrides and metal oxides : their application in area selective ALD
(Bilkent University, 2017-07)III-nitride compound semiconductor materials (GaN, AlN, and InN) and their alloys have generated significant interest in both basic research and commercial applications mainly in the field of photonics, energy storage, ... -
Atomic layer deposition of metal oxide thin films and nanostructures
(Bilkent University, 2013)With the continuing scaling down of microelectronic integrated circuits and increasing need for three-dimensional stacking of functional layers, novel or improved growth techniques are required to deposit thin films with ... -
Fabrication of mesoporous metal chalcogenide nanoflake silica thin films and spongy mesoporous CdS and CdSe
(Wiley Online Library, 2012-02-16)Mesoporous silica metal oxide (ZnO and CdO) thin films have been used as metal ion precursors to produce the first examples of mesoporous silica metal sulfide (mesoSiO2@ZnS, meso-SiO2@CdS) or silica metal selenide ... -
High-refractive-index measurement with an elastromeric grating coupler
(Optical Society of America, 2005)An elastomeric grating coupler fabricated by the replica molding technique is used to measure the modal indices of a silicon-on-insulator (SOI) planar waveguide structure. Because of the van der Waals interaction between ... -
Low temperature thin films transistors with hollow cathode plasma-assisted atomic layer deposition based GaN channels
(AIP Publishing LLC, 2014)We report GaN thin film transistors (TFT) with a thermal budget below 250 °C. GaN thin films are grown at 200 °C by hollow cathode plasma-assisted atomic layer deposition (HCPA-ALD). HCPA-ALD-based GaN thin films are found ... -
Micro and nanostructured devices for thermal analysis
(Bilkent University, 2008)The recent advent of micro and nano devices increased the interest in small scale material properties, such as elasticity, conductivity or heat capacity, which are considerably different from their bulk counterparts due ... -
Molten Salt Assisted Self-Assembly (MASA) : synthesis of mesoporous silica-ZnO and mesoporous CdO thin films
(Bilkent University, 2012)A series of mesostructured salt-silica-two surfactants (salt is [Zn(H2O)6](NO3)2, ZnX or [Cd(H2O)4](NO3)2, CdYand surfactants are cetyltrimethylammonium bromide (CTAB) and 10-lauryl ether, C12H25(OCH2CH2)10OH, C12EO10) ... -
Molten-Salt-Asisted self-Assembly (MASA)-synthesis of mesoporous metal titanate-titania, metal sulfi de-titania, and metal selenide-titania thin films
(Wiley Online Library, 2013)New synthetic strategies are needed for the assembly of porous metal titanates and metal chalcogenite-titania thin films for various energy applications. Here, a new synthetic approach is introduced in which two solvents ... -
The phase behavior and synthesis of mesostructured coupled semiconductor thin films : MESO-CdS-TiO2
(Bilkent University, 2009)Mesostructured [Cd(H2O)4](NO3)2 - titania - P123 ((PEO)20(PPO)70(PEO)20, PEO = -OCH2CH2-, PPO = -OCH(CH3)CH2-) materials have been investigated by changing the [Cd(H2O)4](NO3)2 and titania content of the structures. ... -
RF-sputtering of doped zinc oxides thin films, the effect of low substrate heating deposition
(Bilkent University, 2017-01)Zinc Oxide (ZnO) has been studied since 1930’s as a candidate for the electronic applications, as it possesses a wide bandgap of 3.4 eV. While in the last 3 decades the technology of thin films were more interested in Doped ... -
Synthesis of high temperature wear resistant WC and WN coatings
(Bilkent University, 2012)In this study, WC and WN thin films were synthesized using reactive magnetron sputter deposition in order to develop promising alternatives to the well known wearresistant coatings such as CrN, TiN, TiAlN and TiB2 etc. ...
