Light trapping technology is one of the effective ways to improve the performance of solar
cells, which can enhance the light absorption and reduce the thickness of the material and …

Although there are numerous techniques for the synthesis of plasmonic (metallic Ag and Au)
nanomaterials, eco-friendly and biocompatible methodologies that present diverse …

In this work, an innovative and simple growth approach of two-step solid state dewetting
(SSD) has been introduced for the fabrication of bimetallic and core-shell nanoparticle (NP) …

Black GaAs nanotip arrays (NTs) with 3300 nm lengths were fabricated via self-masked
plasma etching. We show, both experimentally and numerically, that these NTs, with three …

Highly efficient broadband absorbing surfaces covering the UV, visible and near-IR regions
are of great importance for low-light imaging devices, optical devices and optoelectronic …

Light trapping by surface texturing is widely used to improve the performance of
optoelectronic devices. In this Letter, we demonstrate nano/micro dual-scale textured GaAs …

Textured GaAs surfaces with near-zero reflectance are promising for the antireflective
application of photovoltaic and optoelectronic devices. Such surfaces can be described as …

We report the application of gold and silver (AuAg) bimetallic non-alloyed nanoparticles
(BNNPs) on disordered subwavelength structures (d-SWSs). The combined advantages of …

In this paper, the effect of plasmonic metal nanoparticles (MNPs) embedded in GaAs is
investigated via the calculation of scattering and absorption cross sections and the …

ABSTRACT SERS is an effective technique that has the potential to detect the molecules at
ultra-low concentrations and enhance the weak Raman signals [1][2]. Herein, a hybrid …
