Abstract
A device having a semiconductor nanomaterial surface, formed on a dielectric layer, having a conductive material under the dielectric layer, wherein a potential across the dielectric modified an absorption property of the semiconductor nanomaterial. A method of controlling a property of surface is provided, comprising: providing a device having a semiconductor nanomaterial having the surface, formed on a dielectric layer, having a conductive material under the dielectric layer; and controlling an electrostatic field at the semiconductor nanomaterial to modify at least one property of the surface with respect to molecules. The property may be absorption or wetting, for example.
