Surface enhanced infrared absorption with highly doped InAsSb plasmonic nano-antenna arrays

Fernando Gonzalez-Posada Flores

University of Montpellier / CNRS

Dr. Fernando González-Posada received his bachelor in Physics (2003) in the Autonomic University of Madrid and his PhD (2009) in the Polytechnic University of Madrid, working in the design, fabrication and characterisation of high electron mobility transistors based on III-nitrides. In 2011, he joined the Nanophysics and Semiconductors group at CEA-Grenoble. He worked in the design, fabrication and characterization of single GaN nanowires UV photodetectors. He researched one year in Chalmers Technological University focused in solar fuel development based in metallic nanoparticles photocatalysis. Since 2013, he is associate professor of the University of Montpellier and researches in semiconductor plasmonic sensors.


Introduction Resonant surface enhanced infrared absorption (SEIRA) spectroscopy relies on advanced nanofabrication to tailor plasmonic antenna resonances at targeted wavelengths.[1] Strongest signal enhancement is obtained... [ view full abstract ]
