Infrared nano-spectroscopy and imaging of collective superfluid excitations in conventional and high-temperature superconductors
H. T. Stinson, J. S. Wu, B. Y. Jiang +8
We investigate near-field infrared spectroscopy and superfluid polariton imaging experiments on conventional and unconventional superconductors. Our modeling shows that near-field…
Infrared electrodynamics and ferromagnetism in the topological semiconductors BiTe and Mn-doped BiTe
B. C. Chapler, K. W. Post, A. R. Richardella +4
We report on infrared (IR) optical experiments on BiTe and Mn-doped BiTe epitaxial thin films. In the latter film, dilute Mn doping (4.5\%) of the topologically non…
Ferromagnetism and infrared electrodynamics of GaMnAs}
B. C. Chapler, S. Mack, R. C. Myers +7
We report on the magnetic and the electronic properties of the prototype dilute magnetic semiconductor GaMnAs using infrared (IR) spectroscopy. Trends in the ferromagne…
Infrared conductivity of hole accumulation and depletion layers in (Ga,Mn)As- and (Ga,Be)As-based electric field-effect devices
B. C. Chapler, S. Mack, L. Ju +11
We have fabricated electric double-layer field-effect devices to electrostatically dope our active materials, either =0.015 GaMnAs or =3.2 Ga$_{1-x…
An infrared probe of the insulator-to-metal transition in GaMnAs and GaBeAs
B. C. Chapler, R. C. Myers, S. Mack +8
We report infrared studies of the insulator-to-metal transition (IMT) in GaAs doped with either magnetic (Mn) or non-magnetic acceptors (Be). We observe a resonance with a natural…
Reconfigurable Gradient Index using VO2 Memory Metamaterials
M. D. Goldflam, T. Driscoll, B. Chapler +9
We demonstrate tuning of a metamaterial device that incorporates a form of spatial gradient control. Electrical tuning of the metamaterial is achieved through a vanadium dioxide la…
