Analyzing the Optical Properties and Peak Behavior Due to Plasmon Resonance of Silver Cubic-Shape Nanostructures by Means of Discrete Dipole Approximation
In this article, the optical properties of silver cubic-shape nanostructures (SCNs) were analyzed by employing the discrete dipole approximation (DDA) in aqueous media. The absorption, dispersion and extinction cross-sections of these nanostructures were calculated based on the wavelength change of the incident light in the visible and near infrared region. Moreover, the height change, waveleng...

متن کاملNanometre-scale germanium photodetector enhanced by a near-infrared dipole antenna
A critical challenge for the convergence of optics and electronics is that the micrometre scale of optics is significantly larger than the nanometre scale of modern electronic devices. In the conversion from photons to electrons by photodetectors, this size incompatibility often leads to substantial penalties in power dissipation, area, latency and noise. A photodetector can be made smaller by ...
