Ultra-High Precision Radiation Dosimetry via Laser Bleaching the Color Centers in Fast Recovery Optical Fiber Sensors
Ghahrizjani, Reza Taheri; Ameri, Mohsen; Jahanbakhsh, Hossein; Sadeghi, Hossein; Mohajerani, Ezeddin (Institute of Electrical and Electronics Engineers (IEEE), 2020-06-01)
High energy electromagnetic radiation or heavy charged particles are extensively used for medical treatment of certain cancers. Precise prediction or measurements of energy deposition of any types of radiation on tissue is...
Solvent selection for fabrication of low temperature ZnO electron transport layer in perovskite solar cells
Ahmadi, S. Hamideh; Ghaffarkani, Mashhood; Ameri, Mohsen; Safari, Nasser; Mohajerani, Ezeddin (Elsevier BV, 2020-08-01)
Zinc Oxide (ZnO) with an easy synthesis method, low processing temperature, and high charge carrier mobility has been considered as a proper electron transport layer (ETL) for perovskite solar cells. Herein, we investigate...
Performance evaluation of InAs/GaSb superlattice photodetector grown on GaAs substrate using AlSb interfacial misfit array
Korkmaz, Melih; Arikan, Bulent; Suyolcu, Y. Eren; ASLAN, BÜLENT; SERİNCAN, UĞUR (IOP Publishing, 2018-03-01)
We report on the growth and opto-electronic characterization of type-II InAs/GaSb superlattice (SL) mid-wavelength infrared pin photodetector grown on a GaAs substrate. AlSb interfacial misfit array was employed at the GaA...
Phenomenological morphology design of hybrid organic-inorganic perovskite solar cell for high efficiency and less hysteresis
Ameri, Mohsen; Ghaffarkani, Mashhood; Ghahrizjani, Reza Taheri; Safari, Nasser; Mohajerani, Ezeddin (Elsevier BV, 2020-02-01)
In this report, a modeling approach is employed to study the effect of the grain boundaries (GBs) and their electronic activity on the performance parameters of the perovskite solar cells (PSCs). Our model is based on the ...
Direct growth of type II InAs/GaSb superlattice MWIR photodetector on GaAs substrate
SERİNCAN, UĞUR; Arikan, Bulent; Senel, Onur (Elsevier BV, 2018-08-01)
We report on the direct growth and characterization of type-II InAs/GaSb superlattice (T2SL) MWIR photodetector structure grown on a GaAs substrate by molecular beam epitaxy. The designed photodetector structure contains 1...

Eker, Suleyman Umut; Kaldirim, Melih; Sasmaz, Emrah; Demircioğlu, Olgu; Tolunguc, Alp; Asici, Burak; San, Ayse; Barutcu, Berna; Eroglu, Huseyin Cuneyt; Ozer, Selcuk (2018-04-19)
ASELSAN A. S., the largest defense company in Turkey, initiated research activities on developing Mercury Cadmium Telluride (MCT) detectors in 2014. These research activities include bulk crystal growth and surface prepara...
Mechanical and optical properties of SiO2 thin films deposited on glass
Simurka, Lukas; Ctvrtlik, Radim; Tomastik, Jan; Bektaş, Gence; Svoboda, Jan; Bange, Klaus (2018-09-01)
The optical and mechanical properties of amorphous SiO2 films deposited on soda-lime silicate float glass by reactive RF magnetron sputtering at room temperature were investigated in dependence of the process pressure. The...
Integrating National Research Agendas on Solar Heat for Industrial Processes (INSHIP)
Baker, Derek Keıth(2020-12-31)
Despite process heat is recognized as the application with highest potential among solar heating and cooling applications, Solar Heat for Industrial Processes (SHIP) still presents a modest share of about 0.3% of total ins...
