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.
