Abstract:
A hybrid organic-inorganic semiconductor device composed of one or more insulating or semi-insulating layers (1), one conducting semiconductor layer (2), two conducting pads (3), and a layer of multifunctional organic molecules (4), characterized in that:said conducting semiconductor layer (2) is on top of one of said insulating or semi-insulating layers (1), said two conducting pads (3) are on both sides on top of an upper layer which is either said conducting semiconductor layer (2) or another of said insulating or semi-insulating layers (1), making electrical contact with said conducting semiconductor layer (2), and said layer of multifunctional organic molecules (4) is directly bound through at least one functional group to the surface of said upper layer, between the two conducting pads (3), and at least another of said functional groups of said multifunctional organic molecules binds chemicals or absorbs light, wherein said at least one functional group of said multifunctional organic molecules bound to the surface of said upper layer is selected from the group consisting of one or more aliphatic or aromatic carboxyl, thiol, acyclic sulfide, cyclic disulfide, hydroxamic acid and trichlorosilane groups.
