Abstract:
Methods of generating second harmonic generation (SHG) signals from interfaces formed with, or formed over, a noncentrosymmetric material, e.g., α-quartz, are provided. The methods make use of the noncentrosymmetric material as an internal phase reference for the determination of a variety of interfacial electrostatic parameters, including interfacial potential, interfacial charge density, and the sign of the interfacial charge (i.e., net positive or net negative).

Claim (Index 17):
A device comprising:\n a processor; and a computer-readable medium operably coupled to the processor, the computer-readable medium having computer-readable instructions stored thereon that, when executed by the processor, cause an apparatus operably coupled to the device to\n illuminate an interface formed between a noncentrosymmetric material having a selected orientation angle with respect to a reference axis and a different material, or formed between two different materials and disposed over the noncentrosymmetric material, with light having a frequency \u03c9 under conditions to generate a second harmonic generation (SHG) signal having frequency 2\u03c9; \n detect the SHG signal, the SHG signal comprising a bulk second harmonic signal from the noncentrosymmetric material and an interfacial second harmonic signal from the interface; and \n further cause the device to associate the detected SHG signal with an interfacial charge at the interface by comparing the detected SHG signal to a SHG signal generated from a reference interface formed between the noncentrosymmetric material and a reference material at the selected orientation angle.
