Probing charge pumping and relaxation of the chiral anomaly in a Dirac semimetal
Bing Cheng, Timo Schumann, Susanne Stemmer +1
The linear band crossings of 3D Dirac and Weyl semimetals are characterized by a charge chirality, the parallel or anti-parallel locking of electron spin to its momentum. Such mate…
Point group symmetry of cadmium arsenide thin films determined by convergent beam electron diffraction
Honggyu Kim, Manik Goyal, Salva Salmani-Rezaie +4
Cadmium arsenide (Cd3As2) is one of the first materials to be discovered to belong to the class of three-dimensional topological semimetals. Reported room temperature crystal struc…
Soft phonons and ultralow lattice thermal conductivity in the Dirac semimetal Cd3As2
Shengying Yue, Hamid T. Chorsi, Manik Goyal +7
Recently, Cd3As2 has attracted intensive research interest as an archetypical Dirac semimetal, hosting three-dimensional linear-dispersive electronic bands near the Fermi level. Pr…
Efficient Terahertz Harmonic Generation with Coherent Acceleration of Electrons in the Dirac Semimetal Cd3As2
Bing Cheng, Natsuki Kanda, Tatsuhiko N. Ikeda +7
We report strong terahertz (~10^12 Hz) high harmonic generation in thin films of Cd3As2, a three-dimensional Dirac semimetal at room temperature. The third harmonics is detectable…
Basal-plane growth of cadmium arsenide by molecular beam epitaxy
David A. Kealhofer, Honggyu Kim, Timo Schumann +3
(001)-oriented thin films of the three-dimensional Dirac semimetal cadmium arsenide can realize a quantum spin Hall insulator and other kinds of topological physics, all within the…
Synthesis of atomically thin hexagonal boron nitride films on nickel foils by molecular beam epitaxy
S. Nakhaie, J. M. Wofford, T. Schumann +5
Hexagonal boron nitride (h-BN) is a layered two-dimensional material with properties that make it promising as a dielectric in various applications. We report the growth of h-BN fi…
