Systematic optical study of high-x InxGa1-xAs/InP structures for infrared photodetector applications
Smiri Badreddine; R.S. Joshya; İlkay Demir; Saidi Faouzi; İsmail Altuntaş; Delphine Lagarde; Cedric Rober; Marie Xavier; Maaref Hassen (10.12.2022)Optical and structural properties in high-x InxGa1-xAs (x > 0.65) samples with varying indium concentration grown on InP (100) substrate are reported. By increasing the indium fraction, it was found by the high-resolution X-ray ... -
Theoretical analyses of the carrier localization effect on the photoluminescence of In-rich InGaAs layer grown on InP
Marwa Ben Arbia; Smiri Badreddine; İlkay Demir; Faouzi Saidi; İsmail Altuntaş; Fredj Hassen; Hassen Maaref (5.01.2022)The free buffer InGaAs/InP structure has been elaborated by Metal Organic Vapor Phase Epitaxy (MOVPE). High indium content is chosen to reduce the bandgap energy of the ternary material with direct bandgap to be promoted for ...
