Photoluminescence and optical absorption in glassy AsxSe1−x

Structural, dynamic, electronic, and vibrational properties of flexible, intermediate, and stressed rigid As-Se glasses and liquids from first principles molecular dynamics

“…They are used as starting materials in bulk or thin film form, and serve for the design of a certain number of promising optoelectronic applications. [1][2][3][4] As a result, the number of studies under various conditions and forms have increased substantially in the recent years [5][6][7] with special emphasis on the giant photoplasticity that is typical of these materials.…”

The localization of electrons in amorphous semiconductors: A twenty-first century perspective

“…Although the vast majority of chalcogenide glasses behave this way, some technologically important systems do not [36]. Qualitatively, the cross over from systems like Se to those like a-Si:H depends on the 'stiffness' of the lattice, which can be roughly judged by the average local coordination number for the atoms in the amorphous solid, n av .…”
