- •
The native structure and defects in single crystalline Na-doped SnSe were studied.
- •
In-situ STEM and EDS analysis on the thermal stability of Na-SnSe.

Element segregation and evaporation happened in nano-sized sample during annealing.
- •
Bulk Na-SnSe shows relatively better thermal stability during thermal cycles.
