Acceptor formation in Mg-doped, indium-rich GaxIn1-xN: evidence for p-type conductivity
Balkan, Naci; Tıraş, Engin; Erol, Ayşe; Güneş, Mustafa; Ardalı, Şükrü; Arıkan, Çetin; Gümüş, Cebrail (Springer, 2012)We report on the Mg-doped, indium-rich Ga (x) In1-x N (x < 30). In the undoped material, the intrinsic electron density is very high and as a result there is no detectable photoconductivity (PC) signal within the range of ... -
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 ...
