Surface and Bulk Plasmon Excitation on Aluminum Surface at Small to High Grazing Angles
Atoms, 2022 We present a series of spectra measured by reflected electron energy loss spectroscopy on an aluminum sample using a cylindrical mirror analyzer. The measurements were performed in the energy range between 250 eV and 2000 eV and with various incident ...

Advanced Functional Materials, EarlyView.This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

Gold nano-ripple structure with potential for bio molecular sensing applications
Sensing and Bio-Sensing Research, 2016 We introduce a simple and cost-effective scheme for bio-sensing using nano-ripple structures. One dimensional metallic nano-ripple structures formed by gas cluster ion beam irradiation have shown polarization of light as well as localized surface plasmon

Giant THz surface plasmon polariton induced by high-index dielectric metasurface
, 2017 We use computational approaches to explore the role of a high-refractive-index dielectric TiO2 grating with deep subwavelength thickness on InSb as a tunable coupler for THz surface plasmons.

Surface plasmons on a quasiperiodic grating [PDF]
The European Physical Journal B - Condensed Matter and Complex Systems, 2003 A method is presented for calculating the frequencies of non-retarded surface plasmons propagating on a semi-inifinite medium with a surface profile described by a one-dimension quasiperiodic function. The profiles are generated, in analogy with previous work on quasiperiodic superlattices, by repeating unitary cells constructed according to an ...

Advanced Healthcare Materials, EarlyView.A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.

Surface plasmon enhanced infrared photodetection
Opto-Electronic Advances, 2019 infrared photodetectors have been used extensively in biomedicine, surveillance, communication and astronomy. however, state of the art technology based on Ⅲ-Ⅴ and Ⅱ-Ⅵ compounds still lacks excellent performance for high-temperature operation.
