In this 2-presentation webinar, speakers discuss (1) fundamental aspects and capabilities of the probes used to measure interfacial charge transfer at the semiconductor-catalyst-interface and (2) new capabilities for nanoelectrical characterization in liquid.
In this two-presentation webinar, our speakers discuss:
In the first part of the presentation, Michael Nellist (Ph.D. student at the University of Oregon) explains how the pursuit of new insights in solar water splitting research requires unique experimental approaches — including using nanoelectrode AFM-SECM probes, to scan the surface of water-splitting photoanodes, and making in-operando local surface potential measurements. This part of the webinar also explores interfacial charge transfer at the semiconductor-catalyst interface, an issue that is central for solar water splitting yet has been poorly understood. This presentation describes the relevant applications in context alongside the fundamental aspects and capabilities of the probes used. To accomplish this, the speaker reviews:
In the second part of the presentation, Dr. Teddy Huang (Bruker) explores why nanoscale electrical measurements with AFM are common in air, yet extremely challenging in liquid, as well as the new capabilities for nanoelectrical characterization in liquid provided by Bruker's AFM instruments.
This webinar demonstrates how Bruker's AFM innovations enable a whole range of new electrical measurements in liquid, including in-situ piezoelectric response, conductivity and Kelvin probe force mapping, with benefits for research in solar water splitting and other diverse applications such as Li-ion batteries, electrocatalysis, to semiconductors, and bioelectricity.
