    • Common white light sources 

      Erdem, Talha; Demir, Hilmi Volkan (Springer, 2019-01)
      In this Chapter we describe the features of common light sources. We first present the spectral features of the sun and discuss its colorimetric properties. Next, we summarize the properties of traditional light sources ...
    • Electric field dependent optoelectronic nature of InGaN/GaN quantum structures and devices 

      Sarı, Emre (Bilkent University, 2012)
      In the past two decades we have been witnessing the emergence and rapid development of III-Nitride based optoelectronic devices including InGaN/GaN light-emitting diodes (LEDs) and laser diodes with operation ...
    • Electroluminescence efficiency enhancement in quantum dot light-emitting diodes by embedding a silver nanoisland layer 

      Yang, X.; Hernandez-Martinez, P. L.; Dang C.; Mutlugün, E.; Zhang, K.; Demir, Hilmi Volkan; Sun X. W. (Wiley-VCH Verlag, 2015)
      A colloidal quantum dot light-emitting diode (QLED) is reported with substantially enhanced electroluminescence by embedding a thin layer of Ag nanoislands into hole transport layer. The maximum external quantum efficiency ...
    • Introduction 

      Erdem, T.; Demir, Hilmi Volkan (Springer, Singapore, 2019)
      Here we briefly emphasize the importance of lighting for our daily lives as well as its role in energy consumption. We very briefly introduce the problems that need to be addressed and finally summarize the contents of this brief.
    • Near-UV InGaN/GaN-based dual-operation quantum optoelectronic devices 

      Özel, Tuncay; Sarı, Emra; Nizamoğlu, Sedat; Demir, Hilmi Volkan (SPIE, 2007)
      We present a novel dual-operation InGaN/GaN based quantum optoelectronic device (QOD) that operates as a quantum electroabsorption modulator in reverse bias and as a light emitter in forward bias in the spectral range of ...
