Carrier emission of n-type Gallium Nitride illuminated by femtosecond laser pulses
Runze Li, Pengfei Zhu, Jie Chen +3
The carrier emission efficiency of light emitting diodes is of fundamental importance for many technological applications, including the performance of GaN and other semiconductor…
Growth of EuO single crystals at reduced temperatures
Daniel C. Ramirez, Tiglet Besara, Jeffrey B. Whalen +1
Single crystals of (EuBa)O have been grown in a molten barium-magnesium metal flux at temperatures up to 1000°C, producing single crystals of (EuBa)O with b…
The interface between SrRuO and Ru-metal inclusion--Implications for its superconductivity
Soham S. Ghosh, Yan Xin, Zhiqiang Mao +1
Under various conditions of the growth process, when the presumably unconventional superconductor SrRuO (SRO) contains micro-inclusions of Ru metal, the superconducting cri…
Field induced topological phase transition from a three-dimensional Weyl semimetal to a two-dimensional massive Dirac metal in ZrTe5
Guolin Zheng, Xiangde Zhu, Yequn Liu +10
Symmetry protected Dirac semimetals can be transformed into Weyl semimetals by breaking the protecting symmetry, leading to many exotic quantum phenomena such as chiral anomaly and…
Coexistence of Weyl Physics and Planar Defects in Semimetals TaP and TaAs
Tiglet Besara, Daniel A. Rhodes, Kuan-Wen Chen +10
We report a structural study of the Weyl semimetals TaAs and TaP, utilizing diffraction and imaging techniques, where we show that they contain a high density of defects, leading t…
Nearly massless Dirac fermions hosted by Sb square net in BaMnSb2
Jinyu Liu, Jin Hu, Huibo Cao +8
Layered compounds AMnBi2 (A=Ca, Sr, Ba, or rare earth element) have been established as Dirac materials. Dirac electrons generated by the two-dimensional (2D) Bi square net in thes…
Electron-hole asymmetry, Dirac fermions, and quantum magnetoresistance in BaMnBi2
Lijun Li, Kefeng Wang, D. Graf +3
We report two-dimensional quantum transport and Dirac fermions in BaMnBi2 single crystals. BaMnBi2 is a layered bad metal with highly anisotropic conductivity and magnetic order be…
Temperature-driven massless Kane fermions in HgCdTe crystals: verification of universal velocity and rest-mass description
F. Teppe, M. Marcinkiewicz, S. S. Krishtopenko +15
It has recently been shown that the electronic states in bulk gapless HgCdTe offer another realization of pseudo-relativistic three-dimensional particles in a condensed matter syst…
Uncovering the behavior of Hf2Te2P and the candidate Dirac metal Zr2Te2P
K. -W. Chen, S. Das, D. Rhodes +6
Results are reported for single crystal specimens of HfTeP and compared to its structural analogue ZrTeP, which was recently proposed to be a potential reservoir fo…
Incommensurate crystal supercell and polarization-flop observed in the magnetoelectric ilmenite, MnTiO3
Harlyn J. Silverstein, Elizabeth Skoropata, Paul M. Sarte +6
MnTiO3 has been studied for many decades, but it was only in the last few years that its strong magnetoelectric behavior had been observed. Here, we use neutron scattering on two s…
Phase Separation and Superparamagnetism in the Martensitic Phase of
S. Yuan, P. L. Kuhns, A. P. Reyes +5
shape memory alloys in the approximate range display desirable properties for applications as well as intriguing magnetism. These o…
Canted Magnetic Ground State of Quarter-Doped Manganites CaMnO ( = Y, Tb, Dy, Ho, and Er)
R. Sinclair, H. B. Cao, V. O. Garlea +6
Polycrystalline samples of the quarter-doped manganites CaMnO ( = Y, Tb, Dy, Ho, and Er) were studied by X-ray diffraction and AC/DC susceptibility measur…
