Abstract

Integrated submicroelectrodes for combined AFM-SECM measurements are characterized with numerical simulations using the boundary element method. SECM approach curves and SECM images are calculated and analyzed for a model substrate containing pronounced topographical and electrochemical features. The theoretically calculated image has been compared to the experimental data and shows excellent quantitative agreement. Hence, the applicability of integrated AFM-SECM electrodes for combined electrochemical and topographical imaging and a profound theoretical description including quantification of the obtained results are demonstrated.

摘要

用于原子力显微镜-扫描电化学显微镜（AFM-SECM）联合测量的集成亚微电极通过使用边界元法的数值模拟进行表征。针对包含明显地形和电化学特征的模型基底，计算并分析了SECM进近曲线和SECM图像。将理论计算图像与实验数据进行了比较，结果显示出极佳的定量一致性。因此，证明了集成AFM-SECM电极在电化学和地形联合成像方面的适用性以及包括对所得结果进行量化的深入理论描述。
