ABSTRACT:
A semiconductor sensing device for sensing presence, absence or level of species-of-interest in the environment is disclosed. The semiconductor sensing device comprises at least one layer of molecules deposited thereon. The molecules are electrically-responsive to the species-of-interest in a manner such that when the molecules interact with the species-of-interest, a reverse breakdown voltage characterizing the semiconductor sensing device is modified.
