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 Li mitations are discussed and high-frequency artifacts arising from appa ratus contributions are investigated as they pertain to accurate imped ance measurements of materials systems. Remediation strategies are pre sented, including geometrical adjustments, lead shielding, and null-co rrection procedures.
