The motivation for understanding the physics and chemistry of the SiO 2 /Si interface lies in the pivotal role it plays in current metal-oxide-semiconductor (MOS) technology. In this paper, we are concerned with the chemical structure of this interface and its relationship to both MOS device processing chemistry and, ultimately, the resultant …

For example, diverse nanostructured Si (0D, 1D, 2D, and 3D), Si/metal nanocomposites, and Si/C nanocomposites show improved battery performance. However, these methods cannot form stable SEI on the surface of Si, which is another important reason for the failure of Si anode. Experimental results show that surface modification is …

$begingroup$ And to complicate all this, there's a thing called a "Fermi level" (of which I cannot remember all the details) that bends the bandgap of the semiconductor where it's in contact with the metal; this changes the behavior at the interface in complicated ways, up to and including making the junction rectifying (as with a Shottky diode). So you …
