Article Synopsis
- The paper explores how strain affects the structural, electronic, and phonon properties of the SrBaSn half Heusler compound, highlighting its stability based on chemical thermodynamics.
- When subjected to uniform strain, the compound initially shows a direct bandgap of 0.7 eV, which decreases significantly to 0.19 eV at -12% strain, marking a point of instability.
- In the range of +5% to +8% strain, an indirect bandgap is found, ranging from 0.63 eV to 0.39 eV, but further strain leads to structural destabilization, while the material is generally observed to be ductile based on its elastic parameters.
