In the present study, an optical fiber surface plasmon resonance (SPR) biosensor was developed for measuring time- and concentration-dependent DNA hybridization kinetics. Its design complies with a 3D <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline" id="m1"> <mml:mi>Au</mml:mi> <mml:mo>/</mml:mo> <mml:msub> <mml:mrow> <mml:mi>Al</mml:mi> </mml:mrow> <mml:mn>2</mml:mn> </mml:msub> <mml:mi mathvariant="normal">O</mml:mi> <mml:mn>3</mml:mn> </mml:math> multilayer...
Tin-doped β-Ga2O3 (β-Ga2O3:Sn) films doped with different tin concentrations were deposited on MgO (110) substrates by metal organic chemical vapor deposition (MOCVD) at 700 °C. The effect of doping the structural, electrical and optical properties was investigated. 10% Sn-doped film exhibited best conductivity lowest resistivity about 5.21 × 10−2 Ω cm, which is over ten orders magnitude lower than un-doped film. Micro-structural analysis revealed that Sn content had a clear in-plane...
Since localized surface plasmon (LSP) is capable of generating strong electromagnetic fields, it has achieved extensive applications in surface-enhanced Raman scattering (SERS). As opposed to this, polariton (SPP) been rarely employed for its weak electric field enhancement. The present study proposed an Ag nanoparticles (AgNPs) and multilayer Au/Al2O3 film (MLF) hybrid system, acting as efficient SERS substrate by coupling LSPs SPPs resonances. dispersion relationship indicates that the...
In the present study, a nanoparticle-multilayer metal film substrate was presented with silver nanoparticles (Ag NPs) assembled on multilayer gold (Au) by employing alumina (Al 2 O 3 ) as spacer. The SERS performance of proposed structures determined. It suggested that effect improved increase in number layers, which saturated at four layers. resulted from mutual coupling multiple plasmon modes [localized surface plasmons (LSPs), polaritons (SPPs), well bulk (BPPs)] generated Ag...
Arrayed resonant cavity with outstanding optical trapping ability have received increasing attention in surface-enhanced Raman spectroscopy (SERS). Here, a three-dimensional (3D) composite AgNPs-Al 2 O 3 /Au/inverted patterned sapphire substrate PMMA (IPSSPMMA) flexible system is theoretically and experimentally investigated as SERS sensor. With the help of an effective plasma coupling (localized surface plasmons (LSPs) plasmon polaritons (SPPs)), shown by Finite Element Method, between...
Abstract Electrically modulated surface enhanced Raman scattering (E-SERS) can be able to regulate the plasmon resonance peak of metal nanostructures, further improve detection sensitivity SERS substrate. However, E-SERS substrates require auxiliary equipment provide electrical potential, and most them are non-flexible structure, which limits application in portable, in-situ fast area. Here, we developed an electric field-modulated substrate based on piezoelectric effect by combining PVDF...

A bulk photovoltaic effect (BPVE) in materials without inversion symmetry attracts increasing interest for high-efficiency solar cells beyond the p–n junction paradigm. Herein, we report an experimentally feasible TlNbX4O monolayer (TlNbX4O-ML, X = Cl, Br, I) with a large ferroelectric polarization. Using first-principles calculations, demonstrate that TlNbX4O-MLs are semiconductors moderate switching barriers and higher spontaneous polarizations. Furthermore, observe fairly giant shift...
