Abstract

Overlooked apparatus (cabling, leads, sample holder) contributions to experimental impedance spectra can be significant, especially at high frequencies, and can obscure the true sample response. Instrumental limitations are discussed and high-frequency artifacts arising from apparatus contributions are investigated as they pertain to accurate impedance measurements of materials systems. Remediation strategies are presented, including geometrical adjustments, lead shielding, and null-correction procedures.
