Quantitative infrared nanoscopy: Probe-cavity eigenmodes and nano-gap polaritons for strongly coupled nanoscale optics
Benjamin Allen, Brayden Lukaskawcez, Alyssa Bragg +7
Optical nanoscopies including near-field optical microscopy and spectroscopy circumvent the diffraction limit of conventional optics thanks to the nanoscale light focus emerging at…
Mechanically Exfoliated Metallic Delafossite PdCoO2 Nanomembranes: Quantum Transport and Electrical Evaluation Toward Interconnect Applications
Chengyu Zhu, Pahuni Jain, Yi Zhang +6
Metallic delafossite oxides have drawn attention for their ultralow resistivity and coherent electronic transport. However, mesoscopic transport studies are hindered by the limited…
Machine Learning-Assisted Nano-imaging and Spectroscopy of Phase Coexistence in a Wide-Bandgap Semiconductor
Alyssa Bragg, Fengdeng Liu, Zhifei Yang +10
Wide bandgap semiconductors with high room temperature mobilities are promising materials for high-power electronics. Stannate films provide wide bandgaps and optical transparency,…
Interfacial strong coupling and negative dispersion of propagating polaritons in freestanding oxide membranes
Brayden Lukaskawcez, Shivasheesh Varshney, Sooho Choo +12
Membranes of complex oxides like perovskite SrTiO3 extend the multi-functional promise of oxide electronics into the nanoscale regime of two-dimensional materials. Here we demonstr…
Dual Optical Hyperbolicity of PdCoO and PdCrO Delafossite Single Crystals
Salvatore Macis, Annalisa DArco, Eugenio Del Re +12
Hyperbolic materials exhibit a very peculiar optical anisotropy with simultaneously different signs of the dielectric tensor components. This anisotropy allows the propagation of e…
