Reversible Modulation of Thermal Conductivity in GaN via Strain-Driven Reorganization of Dislocation Ensembles
Shantal Adajian, Fanghao Zhang, Zeyu Xiang +5
Crystalline defects are generally regarded as static phonon scatterers that irreversibly suppress thermal transport. Here we show that elastic strain can dynamically and reversibly…
Magnetic Polarons Enable Exceptional Magnetocaloric Response
Joshua Ancheta, Caeli Benyacko, Fanghao Zhang +2
Magnetocaloric materials are typically limited by a trade-off between magnetic entropy and field responsiveness. Here we show that magnetic polarons provide an intermediate regime…
Atomic-scale tunable phonon transport at tailored grain boundaries and Their Impact on Thermal Conductivity
Xiaowang Wang, Chaitanya A. Gadre, Wanjuan Zou +16
Grain boundaries (GBs) strongly influence thermal transport in crystalline solids by disrupting lattice periodicity and scattering phonons. Due to the atomic-level disorder and str…
Coupled Spin-lattice Dynamics across a Magnetostructural Phase Transition
Lokanath Patra, Zeyu Xiang, Yubi Chen +1
First-order magnetostructural phase transitions underpin giant magnetocaloric effects, yet the microscopic role of lattice dynamics in these transitions remains controversial. Here…
Electric-Field-Dependent Thermal Conductivity in Fresh and Aged Bulk Single Crystalline
Fanghao Zhang, Guanchun Rui, Yujie Quan +4
Active thermal management requires advances in thermal switching materials, whose thermal conductivity responds to external stimuli. The electric field, as one of the most convenie…
Lessons from -RuCl3 for pursuing quantum spin liquid physics in atomically thin materials
Claudia Ojeda-Aristizabal, Xiaohu Zheng, Changsong Xu +20
Quantum spin liquids can arise from Kitaev magnetic interactions, and exhibit fractionalized excitations with the potential for a topological form of quantum computation. This revi…
