Photochromism and influence of point defect charge states on optical absorption in aluminum nitride (AlN)
Ivan Gamov, Carsten Hartmann, Thomas Straubinger +1
In this work, we study the absorption properties of AlN in the range of 1.5 - 5.5 eV, as well as the meta-stable change in absorption induced by ultraviolet (UV) irradiation (photo…

Carbon doping of GaN: Proof of the formation of electrically active tri-carbon defects
Ivan Gamov, Eberhard Richter, Markus Weyers +10
Carbon doping is used to obtain semi-insulating GaN crystals. If the carbon doping concentration exceeds , the carbon atoms increasingly form triatomic cluster…
