Broadband staircase quantum well infrared photodetector with low dark current
Ergün, Yüksel; Hoştut, Mustafa; Eker, Süleyman Umut; Sökmen, İsmail (Elsevier Science BV, 2006)We present a theoretical investigation of a novel staircase-like quantum well infrared photodetector (QWIP). It detects wavelengths between 8.8 mu m and 12.3 mu m at an applied electric field of F= 6 x 10(4) V/cm at room ... -
Intersubband electron transition across a staircase potential containing quantum wells: light emission
Ergün, Yüksel; Hoştut, Mustafa; Eker, Süleyman Umut; Sökmen, İsmail (Academic Press LTD Elsevier Science LTD, 2005)We present a theoretical investigation of a novel staircase-like light emitter based on the GaAs/GaxAl1-xAs material system. The emission wavelength is around 12 mum. The device operation is based on the intersubband ... -
A new approach to quantum well infrared photodetectors: Staircase-like quantum well and barriers
Eker, Süleyman Umut; Hoştut, Mustafa; Ergün, Yüksel; Sökmen, İsmail (Elsevier Science BV, 2006)We present a theoretical investigation of a novel staircase-like quantum well infrared photodetector (QWIP). The proposed structure makes use of quantum wells and barriers with increasing Al content both in the wells and ...
