Synthesis of Si-Ge Nanosheets and Their Dispersion of Organic Solvents with Focus on the Hansen Solubility Parameters.

ABSTRACT: Two-dimensional (2D) materials combine the collective advantages of individual building blocks and synergistic properties and have spurred great interest as a new paradigm in materials science. Especially, exfoliation of 2D semiconductive materials into nanosheets is of significance for both fundamental and potential applications. In this report, silicon-germanium (Si-Ge) nanosheets were synthesized by sonication of porous Si-Ge powder. The raw material Si-Ge powder was obtained by leaching Li from Li₁₃Si₂Ge₂ with ethanol; after that, it was crystallized by heat treatment at 500 °C. The thickness and the lateral size of the exfoliated Si-Ge nanosheets were about 3 nm and a few microns, respectively. The nanosheets were dispersed in 55 different organic solv
