Abstract

A new approach for the local deposition of sol-gel films on conducting and insulating surfaces using scanning electrochemical microscopy (SECM) via the feedback and direct modes is presented. Patterning is based on enhancing sol-gel condensation by altering the local pH due to water electrolysis as a result of applying negative potentials.

摘要

本文提出了一种利用扫描电化学显微镜（SECM）通过反馈和直接模式在导电和绝缘表面上局部沉积溶胶-凝胶薄膜的新方法。该方法基于通过施加负电位导致水分解从而改变局部 pH 值来增强溶胶-凝胶缩合来进行图案化。
