Model of Biosensor based on Organic Electrochemical Transistors

A. Shirinskaya [1], Y. Bonnassieux [1], G. Horowitz [1],
[1] LPICM, CNRS, Ecole Polytechnique, Université Paris Saclay, Palaiseau, France

One of the most promising categories of semiconductor-based sensors is organic electrochemical transistor (OECT), which consists of three electrodes (Source, Drain and Gate) and two active layers: electrolyte and conductive polymer. Despite the fact that OECT attracts a lot of attention ... Read More

Modeling Optical Nanoantenna Arrays with COMSOL Multiphysics

Z. Liu[1], X. Ni[1], and A. Kildishev[1]
[1]School of Electrical and Computer Engineering and Birck Nanotechnology Center, Purdue University, West Lafayette, Indiana, USA

Optical nanoantennas have been of great interest recently due to their ability to support a highly efficient, localized surface plasmon resonance and produce significantly enhanced and highly confined electromagnetic fields. Such enhanced local fields have many applications such as ... Read More

Spectroscopic Modeling of Photoelectrochemical Water Splitting

P. Cendula [1], J. O. Schumacher [1],
[1] Institute of Computational Physics, Zurich University of Applied Sciences, Winterthur, Switzerland

A photoelectrochemical (PEC) cell uses solar energy to split water to hydrogen and oxygen in single integrated device. Electrochemical impedance spectroscopy is a suitable tool to characterize recombination and reaction mechanisms in PEC cell. Full numerical drift-diffusion calculations ... Read More

Highly Sensitive Grating-Coupled Bloch Surface Wave Resonance Biosensor via Azimuthal Interrogation

V. Koju [1], W. M. Robertson [1],
[1] Middle Tennessee State University, Murfreesboro, TN, USA

A dielectric multilayer structure, with a grating profile on the surface layer, can couple light into a strongly confined surface wave, known as a Bloch surface wave. These surface modes can be used to design bio-sensors. The corrugated surface structure also enables azimuthal angular ... Read More
