2.7.1.2 Surface treatments of metal-semiconductor
interfaces
To functionalize the semiconductor/contact interface follows
what already seen for surface’s treatments of gate insulator. For
example, in [39], the surface of Gold electrodes in an OTFT is
functionalized through different treatments: thiophenol, 2mercaptoethanesulfonic
acid and thioketone (see the structure in
figure 37). In table 2, these treatments are referred with numbers (1),
(2) and (3).
