Optical transmittance, reflectance, diffusion

Optical transparency and band gap estimation is an essential study for Gallium Oxide thin films.  GEMaC has Perkin Elmer LAMBDA 950 2-ways spectrophotometer, that is equipped with modules for transmission, reflection or diffusion, for the measurements of the transmittance and the reflectance in 200 – 3300 nm wavelength range and 10 – 770 K temperature interval.

Photoluminescence spectroscopy (PL):

For point defect identification study along with electrical characterization, PL spectroscopy measurement are very important. GEMaC has a home-built photoluminescence set-up, with broad wavelength range: 266 – 1000 nm of excitation and 10 – 430 K temperature range.
