Enabling the Ambient Pressure Growth of ScB2 Crystals for AlGaN Power Electronics
Satya K. Kushwaha, Ahamed Raihan, Astrid D. Kengne +19
Here we report the growth of single crystalline ScB2, an ultrahigh-temperature ceramic, at ambient pressure in a laser-heated Optical Floating Zone via the travelling solvent metho…
Role of matrix elements in the time-resolved photoemission signal
F. Boschini, D. Bugini, M. Zonno +17
Time- and angle-resolved photoemission spectroscopy accesses the ultrafast evolution of quasiparticles and many-body interactions in solid-state systems. However, the momentum- and…
Realization of a Type-II Nodal-Line Semimetal in MgBi
Tay-Rong Chang, Ivo Pletikosic, Tai Kong +9
Nodal-line semimetals (NLSs) represent a new type of topological semimetallic beyond Weyl and Dirac semimetals in the sense that they host closed loops or open curves of band degen…
Anisotropic magnetic properties of the ferromagnetic semiconductor CrSbSe
Tai Kong, Karoline Stolze, Ni Danrui +2
Single crystals of CrSbSe, a structurally pseudo-one-dimensional ferromagnetic semiconductor, were grown using a high-temperature solution growth technique and were characteriz…
Non-Magnetic Half-Metals
Zhonghao Liu, Setti Thirupathaiah, Alexander Yaresko +4
Half-metals are a class of materials that are metallic only for one spin direction, and are essential for spintronics applications where one needs to read, write, store and transfe…
Growth, Crystal Structure and Magnetic Characterization of Zn-Stabilized CePtIn4
Elizabeth M. Carnicom, Tomasz Klimczuk, Fabian von Rohr +6
The growth and characterization of CePtIn4, stabilized by 10% Zn substitution for In, is reported. The new material is orthorhombic, space group Cmcm (No. 63), with lattice paramet…
Gate Tunable Magneto-resistance of Ultra-Thin WTe2 Devices
Xin Liu, Zhiran Zhang, Chaoyi Cai +8
In this work, the magneto-resistance (MR) of ultra-thin WTe2/BN heterostructures far away from electron-hole equilibrium is measured. The change of MR of such devices is found to b…
Imaging electronic states on topological semimetals using scanning tunneling microscopy
Andras Gyenis, Hiroyuki Inoue, Sangjun Jeon +12
Following the intense studies on topological insulators, significant efforts have recently been devoted to the search for gapless topological systems. These materials not only broa…
Time-Reversal-Breaking Weyl Fermions in Magnetic Heusler Alloys
Zhijun Wang, M. G. Vergniory, S. Kushwaha +6
Weyl fermions have recently been observed in several time-reversal-invariant semimetals and photonics materials with broken inversion symmetry. These systems are expected to have e…
Temperature-field phase diagram of extreme magnetoresistance in lanthanum monopnictides
F. F. Tafti, Q. D. Gibson, S. K. Kushwaha +3
The recent discovery of extreme magnetoresistance in LaSb introduced lanthanum monopnictides as a new platform to study topological semimetals (TSMs). In this work we report the di…
MoTe2: A Type-II Weyl Topological Metal
Zhijun Wang, Dominik Gresch, Alexey A. Soluyanov +6
Based on the ab initio calculations, we show that MoTe2, in its low-temperature orthorhombic structure characterized by an X-ray diffraction study at 100 K, realizes 4 type-II Weyl…
Resonance-state-induced superconductivity at high Indium contents in In-doped SnTe
Neel Haldolaarachchige, Quinn Gibson, Weiwei Xie +3
We report a reinvestigation of superconducting SnInTe at both low and high In doping levels. Analysis of the superconductivity reveals a fundamental change as a funct…
Consequences of breaking time reversal symmetry in LaSb: a resistivity plateau and extreme magnetoresistance
F. F. Tafti, Q. D. Gibson, S. K. Kushwaha +2
Time reversal symmetry (TRS) protects the metallic surface modes of topological insulators (TIs). The transport signature of robust metallic surface modes of TIs is a plateau that…
