Towards Object Segmentation Mask Selection Using Specular Reflections
Katja Kossira, Yunxuan Zhu, Jürgen Seiler +1
Specular reflections pose a significant challenge for object segmentation, as their sharp intensity transitions often mislead both conventional algorithms and deep learning based m…
On-chip Single-crystal Plasmonic Optoelectronics for Efficient Hot Carrier Collection and Photovoltage Detection
Yunxuan Zhu, Sai. C. Yelishala, Shusen Liao +3
Large-area chemically synthesized single-crystal metals with nanometer-scale thickness have emerged as promising materials for on-chip nanophotonic applications, owing to their sup…
Overcoming the surface paradox: Buried perovskite quantum dots in wide-bandgap perovskite thin films
Hao Zhang, Altaf Pasha, Isaac Metcalf +25
Colloidal perovskite quantum dots (PQDs) are an exciting platform for on-demand quantum, and classical optoelectronic and photonic devices. However, their potential success is limi…
Quantifying efficiency of remote excitation for surface enhanced Raman spectroscopy in molecular junctions
Shusen Liao, Yunxuan Zhu, Qian Ye +4
Surface-enhanced Raman spectroscopy (SERS) is enabled by local surface plasmon resonances (LSPRs) in metallic nanogaps. When SERS is excited by direct illumination of the nanogap,…
