I-V characterization of a quantum well infrared photodetector with stepped and graded barriers
Nutku, Ferhat; Erol, A.; Güneş, M.; Buklu, L. B.; Ergün, Y.; Arıkan, M. C. (Academic Press LTD- Elsevier Science LTD, 2012)I-V characterization of an n-type quantum well infrared photodetector which consists of stepped and graded barriers has been clone under dark at temperatures between 20-300 K. Different current transport mechanisms and ... -
I-V characterization of a staircase quantum well infrared photodetector
Nutku, Ferhat; Arıkan, M. Çetin; Erol, Ayşe; Ergün, Yüksel; Kendirlik, E. Metin (Wiley-V C H Verlag GMBH, 2011)In this work, a quantum well infrared photodetector structure which consists of three different well thicknesses with three different barrier compositions producing a staircase-like conduction band profile with the reputation ... -
A study of photomodulated reflectance on staircase-like, n-doped GaAs/Al (x) Ga1-x As quantum well structures
Dönmez, Ömer; Nutku, Ferhat; Erol, Ayşe; Arıkan, Çetin M.; Ergün, Yüksel (Springer, 2012)In this study, photomodulated reflectance (PR) technique was employed on two different quantum well infrared photodetector (QWIP) structures, which consist of n-doped GaAs quantum wells (QWs) between undoped Al (x) Ga1-x ... -
Zero-bias offsets in I-V characteristics of the staircase type quantum well infrared photodetectors
Nutku, Ferhat; Erol, Ayşe; Arıkan, M. Çetin; Ergün, Yüksel (Elsevier Science BV, 2014)In this work, observed zero-bias offsets in I-V characteristics and differences in J-V characteristics of staircase quantum well infrared photodetectors were investigated. Temperature and voltage sweep rate dependence of ...
