Nanoscale Inhomogeneities Mapping in Ga-Modified Arsenic Selenide Glasses

Nanoscale inhomogeneities mapping in Ga-modified As(2)Se(3) glass was utilized exploring possibilities of nanoindentation technique using a Berkovitch-type diamond tip. Structural inhomogeneities were detected in Ga(x)(As(0.40)Se(0.60))(100−x) alloys with more than 3 at.% of Ga. The appeared Ga(2)Se...

Sumario:Nanoscale inhomogeneities mapping in Ga-modified As(2)Se(3) glass was utilized exploring possibilities of nanoindentation technique using a Berkovitch-type diamond tip. Structural inhomogeneities were detected in Ga(x)(As(0.40)Se(0.60))(100−x) alloys with more than 3 at.% of Ga. The appeared Ga(2)Se(3) nanocrystallites were visualized in Ga-modified arsenic selenide glasses using scanning and transmission electron microscopy. The Ga additions are shown to increase nanohardness and Young’s modulus, this effect attaining an obvious bifurcation trend in crystallization-decomposed Ga(5)(As(0.40)Se(0.60))(95) alloy.
