Article Citation - WoS: 3Citation - Scopus: 4Electrical Characterizations of Schottky Diodes on Ito Modified by Aromatic Sams(Polish Academy of Sciences, 2013) Havare, A. Kemal; Okur, Salih; Yağmurcukardeş, Nesli; Can, M.; Aydın, H.; Şeker, M.; Demiç, ŞerafettinIn order to understand the electronic properties of the organic Schottky diode, ITO/TPD/Al and ITO/SAM/ TPD/Al organic Schottky devices were fabricated to obtain currentffvoltage characteristics. From the slopes and y-axis intercepts of the plots, the values of the ideality factor, barrier heights of the ITO/SAM/TPD/Al diode were determined as 2.03 and 0.56 eV, respectively. The surface characterizations of modified and unmodified ITO were performed via atomic force microscopy.Article Citation - WoS: 12Citation - Scopus: 16Humidity Adsorption Kinetics of a Trypsin Gel Film(Elsevier Ltd., 2012) Okur, Salih; Ceylan, Çağatay; Çulcular, EvrenThis study focuses on the humidity adsorption kinetics of an isopropanol-induced and pH-triggered bovine pancreatic trypsin gel (BPTG). The BPTG was adsorbed on a gold coated Quartz Crystal Microbalance (QCM) substrate with a thickness of 376nm. The morphology of the film was characterized using Atomic Force Microscopy (AFM). QCM was used to investigate the humidity sensing properties of the BPTG film. The response of the humidity sensor was explained using the Langmuir model. The average values of adsorption and desorption rates between 11% RH (relative humidity) and 97% RH were calculated as 2482.5M -1s -1 and 0.02s -1, respectively. The equilibrium constant and average Gibbs Free Energy of humidity adsorption and desorption cycles were obtained as 133,000 and -11.8kJ/mol, respectively. © 2011 Elsevier Inc..
