摘要

铁电极化转换铁电材料扫描探针显微镜在精确测量矫顽电压方面面临挑战，原因是探针尖端和样品表面之间存在介电间隙。在文章编号 2406944 中，Lane W. Martin、Seungbum Hong 及其合作者揭示了该间隙中的不同介电介质如何显著影响测量结果。使用水作为高介电常数介质（ϵr = 79）可以进行更可靠的测量，与传统的基于电容器的研究结果非常接近，为铁电材料的精确定量分析提供了一条途径。

Unveiling the Nanoscale Dielectric Gap and Its Influence on Ferroelectric Polarization Switching in Scanning Probe Microscopy (Adv. Funct. Mater. 11/2025)

Ferroelectric Polarization Switching

Scanning probe microscopy of ferroelectric materials faces challenges in accurately measuring coercive voltages due to the dielectric gap between the probe tip and sample surface. In article number 2406944, Lane W. Martin, Seungbum Hong, and co-workers reveal how different dielectric media in this gap significantly influence measurement outcomes. Using water as a high-permittivity medium (ϵ_r = 79) enables more reliable measurements that closely match conventional capacitor-based studies, providing a pathway to accurate quantitative analysis of ferroelectric materials.
