Photostability of pulsed laser deposited amorphous thin films from Ge-As-Te system

Abstract: Amorphous thin films from Ge-As-Te system were prepared by pulsed laser deposition to study their intrinsic photostability, morphology, chemical composition, structure and optical properties. Photostability of fabricated layers was studied by spectroscopic ellipsometry within as-deposited as well as relaxed (annealed) layers. For irradiation, laser sources operating at three wavelengths in band gap region of the studied materials were employed. The results show that lowest values of photorefraction accompanied… Show more

“…In line with mentioned techniques, pulsed laser deposition (PLD) is a suitable deposition method for the thin films growth too. Favoritism of PLD concerns mainly its simplicity, easy process control, high deposition rate, and often stoichiometric transfer of target material to the films282930. We already reported applicability of PLD for GST films’ fabrication3132.…”

“…На рис. 1 показаны кривые интенсивности дифракции рентгеновских лучей в пленках системы As−Ge−Те с разным содержанием составных элементов, которые хорошо согласуются с результатами работы [8]. Широкие максимумы, наблюдаемые в дифракционной картине, свидетельствуют об аморфности образцов.…”

“…Все данные были получены при комнатной температуре. [8][9][10] и приписан к колебаниям тетраэдров GeTe 4 (симметричный режим растяжения А 1 ), а также симметричным изгибам колебаний пирамид AsTe 3 (мода А 1 ). Пик при 120 см −1 также наблюден в комбинационном спектре тригонального теллура [10].…”
