    • Experimental and theoretical investigation of phosphorus in-situ doping of germanium epitaxial layers 

      Yu, H. -Y.; Battal, E.; Okyay, A., K.; Shim, J.; Park J. -H.; Baek, J. W.; Saraswat, K. C. (Elsevier, 2013)
      We investigate phosphorus in-situ doping characteristics in germanium (Ge) during epitaxial growth by spreading resistance profiling analysis. In addition, we present an accurate model for the kinetics of the diffusion in ...
    • Infrared photoluminescence from TlGaS2 layered single crystals 

      Yuksek, N. S.; Gasanly, N. M.; Aydinli, A.; Ozkan, H.; Acikgoz, M. (Wiley - V C H Verlag GmbH & Co., 2004)
      Photolimuniscence (PL) spectra of TlGaS2 layered crystals were studied in the wavelength region 500-1400 nm and in the temperature range 15-115 K. We observed three broad bands centered at 568 nm (A-band), 718 nm (B-band) ...
    • Low-frequency noise behavior at reverse bias region in InAs/GaSb superlattice photodiodes on mid-wave infrared 

      Tansel, T.; Kutluer, K.; Muti, A.; Salihoglu O.; Aydinli, A.; Turan, R. (2013)
      We describe a relationship between the noise characterization and activation energy of InAs/GaSb superlattice Mid- Wavelength-Infrared photodiodes for different passivation materials applied to the device. The noise ...
    • Surface recombination noise in InAs / GaSb superlattice photodiodes 

      Tansel, T.; Kutluer, K.; Muti, A.; Salihoglu, Ö.; Aydinli, A.; Turan, R. (IOP Institute of Physics Publishing, 2013)
      The standard Schottky noise approach alone is not sufficient to describe the noise mechanism in an InAs/GaSb superlattice photodetector at reverse negative bias. The additional noise identified appears at surface activation ...
    • Thermally stimulated currents in layered Ga4SeS3 semiconductor 

      Aytekin, S.; Yuksek, N.S.; Goktepe, M.; Gasanly, N.M.; Aydinli, A. (2004)
      Thermally stimulated current (TSC) measurements are carried out on nominally undoped Ga4SeS3 layered semiconductor samples with the current flowing along the c-axis in the temperature range of 10 to 150 K. The results are ...
    • XPS and water contact angle measurements on aged and corona-treated PP 

      Süzer, S.; Argun, A.; Vatansever, O.; Aral, O. (John Wiley & Sons, Inc., 1999)
      Effects of corona treatment and aging on commercially produced corona discharged polypropylene (PP) films were followed via surface sensitive roughness analysis by atomic force microscopy (AFM), water contact angle (WCA), ...
