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…
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…
Fast nanothermometry based on direct electron detection of electron backscattering diffraction patterns
Ryan Gnabasik, Razan O. Nughays, Ashlynn Overholser +5
Accurate temperature measurement at the nanoscale is crucial for thermal management in next-generation microelectronic devices. Existing optical and scanning-probe thermometry tech…
Thermal conductivity of boron arsenide above 2100 watts per meter per Kelvin at room temperature
Ange Benise Niyikiza, Zeyu Xiang, Fanghao Zhang +6
Boron arsenide (BAs) single crystals had been previously reported to have thermal conductivity of 1500 W/mK at room temperature. Now we achieved thermal conductivity above 2100 W/m…
High-throughput Discovery of Anti-gap Semiconductors
Zeyu Xiang, Fanghao Zhang, Bolin Liao
Conventional semiconductors typically have bonding states near the valence band maximum (VBM) and antibonding states near the conduction band minimum (CBM). Semiconductors with the…
ALATDYN: a set of Anharmonic LATtice DYNamics codes to compute thermodynamic and thermal transport properties of crystalline solids
Keivan Esfarjani, Harold Stokes, Safoura Nayeb Sadeghi +6
We introduce a lattice dynamics package which calculates elastic, thermodynamic and thermal transport properties of crystalline materials from data on their force and potential ene…
