What Challenges are Associated with Dielectric Measurements at the Nanoscale?
Dielectric measurements at the nanoscale come with several challenges:
Size Effects: The reduced dimensions of nanomaterials can lead to size-dependent dielectric properties, making it difficult to extrapolate bulk material properties. Surface Effects: Increased surface area can result in significant surface charges, which can alter the dielectric properties of nanomaterials. Measurement Sensitivity: High sensitivity instruments are required to accurately measure the dielectric properties of nanomaterials. Environmental Factors: Nanomaterials can be highly sensitive to environmental conditions such as humidity and temperature, which can affect dielectric measurements.
