In article number 1702990, Peer Fischer, Frank Neubrech, Na Liu, and co-workers fabricate three-dimensional palladium helices by nanoglancing angle deposition exhibiting strong circular dichroism for sensitive hydrogen detection in the flammable range. The linearity of the sensor response is significantly improved using palladiumgold hybrid helices. Such a chiral plasmonic sensor scheme is of potential interest for hydrogen-sensing applications, where good linearity and high sensitivity are required.
