Au-Ag binary alloys on n-GaAs substrates and effect of work functions on Schottky barrier height
Akkaya, Abdullah (Springer, 2021)In this study, I investigated the effect of work function (phi(m)) of AuxAg1-x (x = 0, 0.22, 0.37, 0.71 and 1) on the Au-Ag/n-GaAs Schottky diode (SD) parameters. Ag, Au metals and three alloys with different compositions ... -
Comparative study of Ti/Al and Ti/Al/Ti/Au ohmic contacts to AlGaN/ GaN heterostructures
Canbolat, Ayşe; Akkaya, Abdullah; Ayyildiz, Enise (Elsevier, 2024)We investigated the electrical properties and the ohmic contact formation considering Ti/Al and Ti/Al/Ti/Au ohmic contact metallization schemes on AlGaN/GaN heterostructures. The specific contact resistance of contacts was ... -
Comparison Ofthe Ti/N-Gaas Schottky Contacts' Parameters Fabricated Using Dc Magnetron Sputtering And Thermal Evaporation
Kahveci, Osman; Akkaya, Abdullah; Ayyildiz, Enise; Turut, Abdulmecit (WORLD SCIENTIFIC PUBL CO PTE LTD, 2017)We have fabricated the Ti/n-type GaAs Schottky diodes (SDs) by the DC magnetron deposition and thermal evaporation, cut from the same GaAs substrates, and we have made a comparative study of the current-voltage (I-V) ... -
Effect of post annealing on electrical properties of (Ni/Au)/Al0.20Ga0.80N Schottky contacts
Akkaya, Abdullah; Ayyildiz, Enise (ELSEVIER SCIENCE BV, 2016)The effects of thermal annealing on the electrical properties of Ni/Au Schottky contacts on n-type AlxGa1-xN (x=0.20) were investigated by current-voltage (I-V) and capacitance-voltage (C-V) measurements. The Schottky ... -
Green and cost-effective synthesis of zinc oxide thin films by L-ascorbic acid (AA) and their potential for electronics and antibacterial applications
Tasdemir, Abdulkadir; Akman, Nazife; Akkaya, Abdullah; Aydin, Raşit; Şahin, Bünyamin (Elsevıer Scı Ltd, 2022)The evolution of eco-friendly, green route and cheap technology for synthesizing nanostructured zinc oxide (ZnO) thin films using plant extracts is a promising choice because such materials present a widespread potential for ... -
Investigation of the temperature-dependent electrical properties of Au/PEDOT:WO3/p-Si hybrid device
Keskin, Mine; Akkaya, Abdullah; Ayyildiz, Enise; Oksuz, Aysegul Uygun; Karakus, Mucella Ozbay (SPRINGER, 2019)The electrical properties of Au/PEDOT:WO3/p-Si hybrid devices were studied in terms of current-voltage (I-V) and capacitance-voltage (C-V) measurements. Poly (3,4-ethylene dioxythiophene/tungsten trioxide (PEDOT:WO3) ... -
Nanostructured CuO Thin-Film-Based Conductometric Sensors for Real-Time Tracking of Sweat Loss
Aydin, Raşit; Akkaya, Abdullah; Kahveci, Osman; Sahin, Bünyamin (Amer Chemıcal Soc, 2023)Enhanced sweat sensors lead to real-time, sustained,noninvasivetracking of sweat loss, ensure insight into individual health conditionsat the molecular level, and have obtained prominent interest for theirhopeful implementations ... -
Synthesis of Al and In dual-doped CuO nanostructures via SILAR method: Structural, optical and electrical properties
Kahveci, Osman; Akkaya, Abdullah; Aydın, Raşit; Şahin, B.; Ayyıldız, Enise (Elsevier B.V., 2023)In this article, we investigated the doping characteristics of Al-doped CuO (ACO), and Al/In co-doped CuO (AICO) thin films, which were synthesized on glass substrates, via the solution-based successive ionic layer adsorption ...
