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 ... -
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 ...
