Dual-band InGaAs nBn photodetectors at 2 mu m Şahin, Alper; Gül, Musa Selim; Uzgur, Fatih; Kocaman, Serdar (2022-02-01) An nBn type InGaAs photodetector structure operating at 2 mu m with dual-band operation capability has been numerically designed and experimentally characterized. A compositionally graded and unintentionally doped InGaAlAs...
Barrier engineering for HgCdTe unipolar detectors on alternative substrates Uzgur, Fatih; Kocaman, Serdar (2019-03-01) Delta-doped layers together with compositionally grading have been utilized to get nBn configurations for the HgCdTe material system in all the short-wave (SWIR), medium-wave (MWIR) and long-wave (LWIR) infrared bands. Sho...
A Dual-Band HgCdTe nBn Infrared Detector Design Uzgur, Fatih; Kocaman, Serdar (2019-01-01) Low dark current and/or high operating temperature are the main motivations behind the nBn detector structures where removing the valence band discontinuity is usually an important design challenge. With the utilization of...
InGaAs nBn SWIR detector design with lattice-matched InAlGaAs barrier Uzgur, Fatih; Kocaman, Serdar (2019-01-01) Dark current optimization with band gap engineering has been numerically studied for InGaAs nBn type infrared photodetectors. Undoped InAlGaAs grading layers are utilized in constructing the barrier and dipole delta-doped ...
nBn Detector Designs Basedon Delta Doping andCompositional Grading Uzgur, Fatih; Kocaman, Serdar (null; 2018-06-21)
All InGaAs Unipolar Barrier Infrared Detectors Uzgur, Fatih; Kizilkan, Ekin; Kocaman, Serdar (2018-04-01) Unipolar barrier detector design is a challenge for InGaAs material system since there is a lack of proper barrier material that blocks majority carriers and allows unimpeded flow of minority carriers. As a bandgap enginee...
Al/Sb Free InGaAs Unipolar Barrier Infrared Detectors Uzgur, Fatih; Kizilkan, Ekin; Kocaman, Serdar (2017-04-13) It is numerically shown that Al/Sb free InGaAs unipolar barrier detectors with superior performance compared to the conventional heterojunction detectors can be constructed. Compositionally graded layers provide the transi...
