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…
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…
Mechanisms of skyrmion and skyrmion crystal formation from the conical phase
Taehoon Kim, Haijun Zhao, Ben Xu +6
Real-space topological magnetic structures such as skyrmions and merons are promising candidates for information storage and transport. However, the microscopic mechanisms that con…
Electrical Control of Large Rashba Effect in Oxide Heterostructures
Yan Song, Dong Zhang, Ben Xu +2
Large Rashba effect efficiently tuned by an external electric field is highly desired for spintronic devices. Using first-principles calculations, we demonstrate that large Rashba…
Strong phonon localization in PbTe with dislocations and large deviation to Matthiessen's rule
Yandong Sun, Yanguang Zhou, Jian Han +5
Dislocations can greatly enhance the figure of merit of thermoelectric materials by prominently reducing thermal conductivity. However, the evolution of phonon modes with different…
Possible structural origin of superconductivity in Sr-doped Bi2Se3
Zhuojun Li, Meng Wang, Dejiong Zhang +13
Doping bismuth selenide (Bi2Se3) with elements such as copper and strontium (Sr) can induce superconductivity, making the doped materials interesting candidates to explore potentia…
