Dopant-segregation to grain boundaries controls electrical conductivity of n-type NbCo(Pt)Sn half-Heusler alloy mediating thermoelectric performance
Ting Luo, Federico Serrano-Sánchez, Hanna Bishara +12
Science-driven design of future thermoelectric materials requires a deep understanding of the fundamental relationships between microstructure and transport properties. Grain bound…
Phonon Scattering in the Complex Strain Field of a Dislocation
Yandong Sun, Yanguang Zhou, Ramya Gurunathan +5
Strain engineering is critical to the performance enhancement of electronic and thermoelectric devices because of its influence on the material thermal conductivity. However, curre…
Thermal Resistance at a Twist Boundary and Semicoherent Heterointerface
Ramya Gurunathan, Riley Hanus, Samuel Graham +2
Traditional models of interfacial phonon scattering, including the acoustic mismatch model (AMM) and diffuse mismatch model (DMM), take into account the bulk properties of the mate…
When Band Convergence is Not Beneficial for Thermoelectrics
Junsoo Park, Max Dylla, Yi Xia +3
Band convergence is considered a clear benefit to thermoelectric performance because it increases the charge carrier concentration for a given Fermi level, which typically enhances…
Probing the Phonon Mean Free Paths in Dislocation Core by Molecular Dynamics Simulation
Yandong Sun, Yanguang Zhou, Ming Hu +3
Thermal management is extremely important for designing high-performance devices. The lattice thermal conductivity of materials is strongly dependent on the structural defects at d…
On the Dopability of Semiconductors and Governing Material Properties
Anuj Goyal, Prashun Gorai, Shashwat Anand +3
To be practical, semiconductors need to be doped. Sometimes, to nearly degenerate levels, e.g. in applications such as thermoelectric, transparent electronics or power electronics.…
