THz Near-Field Imaging of Extreme Subwavelength Metal Structures
Xinzhong Chen, Xiao Liu, Xiangdong Guo +15
Modern scattering-type scanning near-field optical microscopy (s-SNOM) has become an indispensable tool in material research. However, as the s-SNOM technique marches into the far-…
Infrared nano-spectroscopy of ferroelastic domain walls in hybrid improper ferroelectric CaTiO
K. A. Smith, E. A. Nowadnick, S. Fan +14
Ferroic materials are well known to exhibit heterogeneity in the form of domain walls. Understanding the properties of these boundaries is crucial for controlling functionality wit…
The insulating phases of vanadium dioxide are Mott-Hubbard insulators
T. J. Huffman, C. Hendriks, E. J. Walter +6
We present the first comprehensive broadband optical spectroscopy data on two insulating phases of vanadium dioxide (VO2): monoclinic M2 and triclinic. The main result of our work…
A broadband silicon quarter-wave retarder for far-infrared spectroscopic circular dichroism
Xiaoxiang Xi, R. J. Smith, T. N. Stanislavchuk +4
The high brightness, broad spectral coverage and pulsed characteristics of infrared synchrotron radiation enable time-resolved spectroscopy under throughput-limited optical systems…
Bulk Signatures of Pressure-Induced Band Inversion and Topological Phase Transitions in PbSnSe
Xiaoxiang Xi, Xu-Gang He, Fen Guan +10
The characteristics of topological insulators are manifested in both their surface and bulk properties, but the latter remain to be explored. Here we report bulk signatures of pres…
Anisotropic Infrared Response of Vanadium Dioxide Microcrystals
T. J. Huffman, Peng Xu, M. M. Qazilbash +8
Vanadium dioxide (VO2) undergoes a phase transition at a temperature of 340 K between an insulating monoclinic M1 phase and a conducting rutile phase. Accurate measurements of poss…
