Electronic contribution in heat transfer at metal-semiconductor and metal silicide-semiconductor interfaces

Ultrafast direct electron transfer at organic semiconductor and metal interfaces

The ability to control direct electron transfer can facilitate the development of new molecular electronics, light-harvesting materials, and photocatalysis. However, control of direct electron transfer has been rarely reported, and the molecular conformation-electron dynamics relationships remain unclear. We describe direct electron transfer at buried interfaces between an organic polymer semic...

Metal-Semiconductor Interfaces in Thin-Film Transistors

The metal-semiconductor interface in thin-film transistors (TFTs) is one of the bottlenecks on the development of these devices. Although this interface does not play an active role in the transistor operation, a low-quality interface can be responsible for a low performance operation. In a-Si TFTs, a doped film can be used to improve this interface, however, in other TFT technologies, there is...

Photoemission Studies of Metal-semiconductor Interfaces

Chemical tuning of metal-semiconductor interfaces.

We report a study of the Schottky barrier for Pb films grown on Si surfaces terminated by various metals (Ag, In, Au, and Pb) to explore the atomic-scale physics of the interface barrier and a means to control the barrier height. Electronic confinement by the Schottky barrier results in quantum well states in the Pb films, which are measured by angle-resolved photoemission. The barrier height i...

The Metal-Semiconductor Interface

Interfaces between metal and semiconductor may be found almost everywhere in contemporary electronics. Often the metal is there just to serve as a contact to p-n junctions in the semiconductor. At other times, the metal-semiconductor interface itself performs essential electronic functions. Considerable scientific interest has been devoted to this latter situation since early in the century, as...
