Versatile fluidic cell for in-situ electrochemical measurements in SEM

Abstract

Electrochemical techniques such as like electrodeposition are crucially important for fabrication of nanostructured materials. The details of cluster nucleation and growth at early stages of electrodeposition are extremely important for morphology and properties of the deposits. The growth mechanism is usually determined by analyzing global electrochemical data in conjunction with ex-situ images. Though this approach gives us a clear picture as a whole, it fails to reveal the evolution of islands morphology at nanoscale and its effects on reaction rate.In this report, we describe novel chip and cell designs enabling us to study electrochemical processes in real time and as a function of temperature using SEM in liquids.
