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…
Reversible Modulation of Thermal Conductivity in GaN through Strain-Field Screening around Dislocations
Shantal Adajian, Fanghao Zhang, Andrew Christison +9
Crystalline defects are generally regarded as static phonon scatterers that irreversibly suppress thermal transport. Here we show that elastic strain can reversibly modify dislocat…
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…
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…
Absence of Phonon Softening across a Charge Density Wave Transition due to Quantum Fluctuations
Yubi Chen, Terawit Kongruengkit, Andrea Capa Salinas +9
Kagome metals have emerged as a frontier in condensed matter physics due to their potential to host exotic quantum states. Among these, CsV3Sb5 has attracted significant attention…
