Organic–inorganic hybrid gas sensors can offer outstanding performance in terms of
selectivity and sensitivity towards single gas species. The enormous variety of organic
functionalities enables novel flexibility of active sensor surfaces compared to commonly
used pure inorganic materials, but goes along with an increase of system complexity that
usually hinders a predictable sensor design. In this work, an ultra‐selective NO2 sensor is
realized based on self‐assembled monolayer (SAM)‐modified semiconductor nanowires …

An ultra-selective NO 2 sensor is designed and realized by JD Prades, H. Shen, and co-
workers based on self-assembled monolayer (SAM)-modified semiconductor nanowires
(NWs). On page 595, consistent experimental sensing evaluations on different gases and
density functional theory (DFT) simulations on the sensing mechanism of the complex NW-
SAM-gas systems are presented. The resulting insight into the charge transfer mechanism
depicts a theoretical route to develop highly selective hybrid gas sensors.
