Low-Temperature Microstructural Studies on Superconducting CaFe₂As₂
(Nature Publishing Group, 2019-04-23)Undoped CaFe₂As₂ (Ca122) can be stabilized in two slightly different non-superconducting tetragonal phases, PI and PII, through thermal treatments. Upon proper annealing, superconductivity with a T_{c} up to 25 K emerges ... -
High Thermal Conductivity in Isotopically Enriched Cubic Boron Phosphide
Zinc blende boron arsenide (BAs), boron phosphide (BP), and boron nitride (BN) have attracted significant interest in recent years due to their high thermal conductivity (Λ) predicted by first-principles calculations. This ... -
High Thermal Conductivity in Cubic Boron Arsenide Crystals
The high density of heat generated in power electronics and optoelectronic devices is a critical bottleneck in their application. New, high thermally-conducting materials are needed to effectively dissipate heat and thereby ... -
Laser Post-Processing of Halide Perovskites for Enhanced Photoluminescence and Absorbance
(IOP Publishing Ltd, 2018-11-05)Hybrid halide perovskites have emerged as one of the most promising type of materials for thin-film photovoltaic and light-emitting devices. Further boosting their performance is critically important for commercialization. ... -
Seeded Growth of Boron Arsenide Single Crystals with High Thermal Conductivity
(Amer Inst Physics, 2018-11-05)Materials with high thermal conductivities are crucial to effectively cooling high-power-density electronic and optoelectronic devices. Recently, zinc-blende boron arsenide (BAs) has been predicted to have a very high ... -
Superconductivity from Site-Selective Ru Doping Studies in Zr₅Ge₃ Compound
(IOP Publishing Ltd, 2018-10-22)Systematical doping studies have been carried out to search for the possible superconductivity in the transition metal doped Zr₅Ge₃ system. Superconductivity up to 5.7 K is discovered in the Ru doped Zr₅Ge₂․₅Ru₀․₅ sample. ... -
Ultrafast Dynamics of Quasiparticles and Coherent Acoustic Phonons in Slightly Underdoped (BaK)Fe₂As₂
(Nature Publishing Group, 2016-05-16)We have utilized ultrafast optical spectroscopy to study carrier dynamics in slightly underdoped (BaK)Fe2As2 crystals without magnetic transition. The photoelastic signals due to coherent acoustic phonons have been ... -
Evidence for Defect-Induced Superconductivity up to 49 K in (Ca₁₋ₓ)Fe₂As₂
(Amer Physical Soc, 2016-02-12)To explore the origin of the unusual nonbulk superconductivity with a T_c up to 49 K reported in the rare-earth-doped CaFe₂As₂, the chemical composition, magnetization, specific heat, resistivity, and annealing effect are ... -
Chemical Doping and High-Pressure Studies of Layered β-PdBi₂ Single Crystals
(American Physical Society, 2015-11-04)We have systematically grown large single crystals of the layered compounds β-PdBi₂, and both the hole-doped PdBi₂₋ₓPb₂ and the electron-doped NaₓPdBi₂, and studied their magnetic and transport properties. Hall effect ...
