I am a physicist. My field of interest is a solid state physics.
Mainly, optical and electrical properties of semiconductors.
Time-resolved luminescence of zinc oxide (ZnO) grown on gallium nitride (GaN) at 4 K.
ZnO and GaN emit light of energies about 3.36 and 3.48 eV, respectively.
ZnO is used as luminophore, GaN is used for production of LEDs and lasers.
