Room-Temperature Terahertz Anomalous Hall Effect in Weyl Antiferromagnet MnSn Thin Films
Takuya Matsuda, Natsuki Kanda, Tomoya Higo +3
Antiferromagnetic spin motion at terahertz (THz) frequencies attracts growing interests for fast spintronics, however their smaller responses to external field inhibit device appli…
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…
Disorder-driven topological phase transition in Bi2Se3 films
Matthew Brahlek, Nikesh Koirala, Maryam Salehi +16
Topological insulators (TI) are a phase of matter that host unusual metallic states on their surfaces. Unlike the states that exist on the surface of conventional materials, these…
Stability of low-carrier-density topological-insulator BiSe thin films and effect of capping layers
Maryam Salehi, Matthew Brahlek, Nikesh Koirala +4
Although over the past number of years there have been many advances in the materials aspects of topological insulators (TI), one of the ongoing challenges with these materials is…
Reduction of Effective Terahertz Focal Spot Size By Means Of Nested Concentric Parabolic Reflectors
V. A. Neumann, N. J. Laurita, LiDong Pan +1
An ongoing limitation of terahertz spectroscopy is that the technique is generally limited to the study of relatively large samples of order 4 mm across due to the generally large…
Broadband microwave and time-domain terahertz spectroscopy of CVD grown graphene
W. Liu, R. Valdés Aguilar, Y. Hao +2
We report a study of the complex AC impedance of CVD grown graphene. We measure the explicit frequency dependence of the complex impedance and conductance over the microwave and te…
