This is a stationary solution electrochemical cell designed to measure characteristics of electrolyte-gated (or solution-gated) transistors using liquid or gel electrolyte. Measured transistor sample can be fabricated on a rigid or flexible flat substrate (not included in the setup) with conducting thin film source and drain, and a layer of conducting or semiconducting channel material.The sample is loaded from the bottom via magnetic (or screw) mount, while gate is mounted in a top casing. A reference electrode can also be mounted in the top casing in case it is needed to control the channel/electrolyte interfacial potential or perform an electrochemical pre-treatment on the channel material. Source and drain electrodes can be accessed through cut-outs in a cell bottom casing, using needle probes or toothless crocodile clips.The cell elements are constructed with materials that are inert to the sample (glass and PEEK). It well fits aqueous (EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight and can be used when the removal and exclusion of contaminants such as oxygen and water is required by bubbling of an inert gas through the electrolyte.Please note: this product is not available from Metrohm Germany.
