Abstract

Here we discuss the synthesis paths and optoelectronic properties in the context of alpha tin (α-Sn) phase and silicon/tin (SiSn) alloyed nanocrystals (NCs). We discuss the possibilities and benefits of stabilizing α-Sn in larger sized nanocrystals by alloying with silicon. We demonstrate that plasma-based processes allow the synthesis of stable elemental α-Sn NCs and also alloyed α-Sn based SiSn NCs with quantum confinement size and extraordinarily high Sn concentrations: i.e. SiSn NCs fabricated by confined plasma from femtosecond (fs) laser in liquid media with a high tin concentration of approximately 17%. We also discuss the experimental and exact theoretical calculation determination of the thermal stability of the α-Sn based nanocrystals.
