EC-STM
In-Operando STM for electrochemistry
Electrochemical Scanning Tunneling Microscopy for solid-liquid interface studies in-operando in correlation with cyclic voltammetry in electrochemical cells.
Leiden Probe Microscopy offers an electrochemical STM to make in-operando electrochemical studies simple.
01 Exchangable Scan heads: Fast or Long
The EC-STM comes with two modules: long range STM and a fast STM. Choose between a scan range of 10 μm or video rate scan speed with 100 fps at 100x100 pixels. Modules can be easily swapped.
02 Environmental control
Control the electrochemical liquids in the cell and the mixture of the gas environment above the cell.
03 Correlative research
The EC-cell infrastrucure is designed with focus on cleanliness, such that proper Cyclic Voltammetry can be correlated with STM. The strength of this instrument is the correlation between the electrochemistry and the surface science.
04 Flag style inserts
Compatibility with custom electrochemical cell design is important in electrochemistry. Therefore, a flag style sample insert is used to quickly insert new experiments without demounting the STM, optionally under protective
05 EC-STM made easy

Typical applications
What our technology can do for you
EC cell customization
For studying electrochemistry, it’s important to design experimental cells specifically for each experiment. Leiden Probe Microscopy brings the flag style sample insert interface to EC-STM. This allows to design your own EC-cell and insert it easily into the EC-STM.
STM probes required for the EC-STM can be prepared with the tip etcher and tip coater dedicated setup. After
performing experiments, EC-cells can be dismounted and cleaned. The liquid inlets are chemically resistant PTFE
and can be properly cleaned after dismounting.
Environmental control
Surfaces can be studied locally in an EC-cell and under a protective gas environment. Inside the enclosed volume around the EC-cell, the gas atmosphere can be filled with pure gasses or a mixture of CO, CO2, H2, and Ar. Temperature and humidity can also be controlled.
The STM head is operated under an Ar environment, such that samples can be transferred via a load-lock under a protective environment. This enables swift and clean sample transfers. The whole instrument is placed in an acoustic enclosure with integrated Faraday cage and active vibration isolation.
