Functionalization of hydrofluoric acid‐etched crystalline silicon surfaces were performed using 4‐aminopyridine. This treatment was employed to perform an organic interface with the exterior ambient. The obtained treated surfaces were exposed to different organic vapors while keeping track of their electric conductance to assess their sensing abilities. Results for these tests are provided.
Porous Silicon sensing devices have been developed and tested in air and pure nitrogen atmospheres containing organic vapors in order to study their electric response. It has been found differences in the electrical behavior of the sensors when subjected to both atmospheres. Possible explanations are proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
