Optical properties of As-Se amorphous composites

Photostructural transformations in amorphous films of chalcogenide glasses (ChG) under light irradiation present scientific and practical interests. That is well known that the composition of ChG determines the kind of structural units and the mean coordination number. In the present work the amorphous films of the chalcogenide systems As100-xSex (x=40÷98), As40Se60:Sny (y=0÷10.0 at.% Sn), as w...

Optical properties of amorphous C/diamond thin films

Amorphous C/diamond films have been prepared by rf plasma enhanced vapor deposition from a CHdAr gas mixture. Infrared and optical-ultraviolet absorption characteristics are reported and used to characterize the bonding and optical properties of these films. It has been found that the optical band gap is not related to the hydrogen content in the films and varies according to the dc self bias d...

Optical and structural properties of amorphous SexTe100-x aligned nanorods

In the present work, we report studies on optical and structural phenomenon in as-deposited thin films composed of aligned nanorods of amorphous SexTe100-x (x = 3, 6, 9, and 12). In structural studies, field emission scanning electron microscopic (FESEM) images suggest that these thin films contain high yield of aligned nanorods. These nanorods show a completely amorphous nature, which is verif...

Mid-infrared transmission properties of amorphous germanium optical fibers

Germanium optical fibers have been fabricated using a high pressure chemical deposition technique to deposit the semiconductor material inside a silica capillary. The amorphous germanium core material has a small percentage of hydrogen that saturates the dangling bonds to reduce absorption loss. Optical transmission measurements were performed to determine the linear losses over a broad mid-inf...
