Complex multi-directional modulated structures induced by coherent gamma-Sb2O3 secondary phase particle in the P-type (Bi,Sb)2Te3 alloy

Key Points

• Multi-directional modulated structures were induced by the coherent gamma-Sb2O3 particles in the p-type alloy.
• Measurements showed that the modulated structures positively affect thermal and electrical properties, enhancing performance.
• Analysis focused on the interaction of coherent secondary phase particles within the host matrix and their effects.
• Significance lies in understanding complex behaviors in thermoelectric materials, which may lead to enhanced applications.
