Abstract

Surface states of inorganic semiconductors may be modified by covalently attaching a monolayer of organic compounds with desired electronic levels. The attached compound, depending on its electron affinity and ionization potential, will withdraw electrons from or donate electrons to the bulk of the semiconductor. Where there is a sufficiently large surface density of well defined electronic levels, the surface state of the semiconductor will be dominated.

Controlling Surface States of Semiconductors

Surface states of inorganic semiconductors may be modified by covalently attaching a monolayer of organic compounds with desired electronic levels. The attached compound, depending on its electron affinity and ionization potential, will withdraw electrons from or donate electrons to the bulk of the semiconductor. Where there is a sufficiently large surface density of well defined electronic levels, the surface state of the semiconductor will be dominated.

The organic monolayer can be attached, for example, as shown in the figure.
