Surface Photovoltage Spectrometer (SPV) Analysis ServiceSurface Photovoltage Spectrometer (SPV) Analysis refers to an approach that uses materials' properties, specifically their' interfacing position, for more schematic electronic studies of complex device structures surfaces. It can be used, for example, for studying semiconductors, thin films, and other complex materials as it provides important information about the dynamics of charge carriers and the energy band, surface states, and defects. SPV Analysis requires illumination of the material with light of different wavelengths which makes it possible to change the surface volume. SPV Analysis permits an effective, but nondestructive method of material characterization.
The underlying concept of SPV Analysis focuses on the photoelectric consumption activity. When a material is exposed to photons of desired energy, electron-hole pairs are formed in the material. These pairs migrate toward the surface or space charge region and produce a surface photovoltage that can be measured. This voltage is measured and graphed against the wavelength of light used, which provides a clear insight into the material's electronic structure. This method is advanced because it responds profoundly to actions taken on the surface and Interface of the material, which is why it is especially helpful for materials with complex electronic structures.
