The rapid characterization of nanoparticles for morphological information such as size and shape is essential material synthesis they are the determining factors optical, mechanical, chemical properties related applications. In this paper, we report a computational imaging platform to characterize nanoparticle morphology under conventional optical microscopy. We established machine learning model based on series images acquired by through-focus scanning microscopy (TSOM) microscope. This...
Controlling the nanoscale light–matter interaction using superfocusing hybrid photonic–plasmonic devices has attracted significant research interest in tackling existing challenges, including converting efficiencies, working bandwidths, and manufacturing complexities. With growth demand for efficient input–output interfaces to improve plasmonic device performances, sophisticated designs with multiple optimization parameters are required, which comes an unaffordable computation cost. Machine...
Fluorescent nanodiamonds (FNDs) with nitrogen-vacancy centers are pivotal for advancing quantum photonics and imaging through deterministic state manipulation. However, integration of emitters into photonic devices remains a challenge due to the need high coupling efficiency Purcell enhancement. We report FND-integrated nanofocusing device achieved by assembling FNDs at plasmonic waveguide tip plasmonic-enhanced optical trapping. This technique not only increases emission rate 58.6 times...
Integrated photodetectors are crucial for their high speed, sensitivity, and efficient power consumption. In these devices, photocurrent generation is primarily attributed to the photovoltaic (PV) effect, driven by electron hole separations, photothermoelectric (PTE) which results from temperature gradients via Seebeck effect. As devices shrink, overlap of mechanisms-both dependent on Fermi level band structure-complicates separate evaluation at nanoscale. This study introduces a novel 3D...
Abstract Spin excitations, including magnons and spinons, can carry thermal energy spin information. Studying spin‐mediated transport is crucial for caloritronics, enabling efficient heat dissipation in microelectronics advanced thermoelectric applications. However, designing quantum materials with controllable challenging.
