Solid State Chemistry

Background:

Arsenic selenide (As2Se3) glasses are known for their optical properties.
Gallium (Ga) modification can alter the structural and mechanical properties of chalcogenide glasses.
Understanding nanoscale properties is crucial for advanced material applications.

Purpose of the Study:

To map nanoscale inhomogeneities in Ga-modified As2Se3 glasses.
To investigate the effect of Ga additions on the mechanical properties of As2Se3 glass.
To explore the utility of nanoindentation for characterizing such materials.

Main Methods:

Nanoindentation using a Berkovitch-type diamond tip.
Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) for visualization.
Compositional analysis of Ga-modified As2Se3 alloys (Ga_x(As0.40Se0.60)100-x).

Main Results:

Structural inhomogeneities were detected in Ga_x(As0.40Se0.60)100-x alloys with >3 at.% Ga.
Ga2Se3 nanocrystallites were visualized within the Ga-modified glasses.
Ga additions increased nanohardness and Young's modulus.
A bifurcation trend in mechanical properties was observed in crystallized-decomposed Ga5(As0.40Se0.60)95 alloy.

Conclusions:

Nanoindentation is effective for mapping nanoscale inhomogeneities in Ga-modified As2Se3 glasses.
Gallium incorporation leads to the formation of Ga2Se3 nanocrystallites and enhances mechanical properties.
The observed bifurcation trend highlights the complex interplay between composition, structure, and mechanical response in these alloys.
