K. Sedeek scite author profile

Optical properties have been studied in amorphous thin films of various Ge-based chalcogenide glasses with a view to investigating the effect of Te isovalence substitution in the Ge-S-Se system. Te either completely replaces S to give Ge2.5Te2.5Se95 and Ge5Te5Se90 or partially replaces Se to give Ge2.5S2.5Te2.5Se92.5 and Ge5S5Te5Se85. The changes recorded for the absorption band edge and for the optical gap width are discussed in terms of the different physical properties of Te with respect to S or Se.
