NILES (National Institute of Laser Enhanced Sciences)

NILES in EGYPT

CAIRO UNIVERSITY

The Laboratory are mainly interested in

"Optical Properties of Semiconductors" 

  • Absorption.
  • Photolumenesence ( PL).
  • Photolumenesence Excitation(PLE).

 

Photoluminesence Experiment

 m - PL Experiment

Nanostructures

Quantum Dots are formed on the surface of Silicon substrate by  DCD technique. The PL and Raman are used to investigate the sample ( Emitted Wavelengths and the size of the formed Dots)
