Measuring the Burgers Vector of Dislocations with Dark-Field X-ray Microscopy
Dayeeta Pal, Yifan Wang, Ramya Gurunathan +1
The behavior of dislocations is essential to understand material properties, but their subsurface dynamics that are representative of bulk phenomena cannot be resolved by conventio…
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…
Analytical Models of Phonon-Point Defect Scattering
Ramya Gurunathan, Riley Hanus, Maxwell Dylla +2
Point defects exist widely in engineering materials and are known to scatter vibrational modes to reduce thermal conductivity. The Klemens description of point defect scattering is…
