Webinar: Boost your Signal-to-Noise Ratio with Lock-in Amplifiers

In this tutorial, we learned how to use lock-in amplifiers and optimize measurement parameters to get the best signal-to-noise ratio. We discussed three common use cases: optics and photonics experiments, material characterization, and resonator characterization. Finally, we looked at more advanced techniques, such as double modulation and multi-frequency measurements.

Resonator Characterization via the Pound-Drever-Hall Method

PDH Block diagram

This blog discusses methods for measuring the frequency fluctuations and quality factor, 𝑄, of a resonator. Resonators are physical systems that naturally oscillate at a well-defined frequency. At this resonant frequency, energy exchanges periodically between two forms, for example, kinetic and spring energy as in a scanning probe microscope’s cantilever...

Swiss chocolates are famous worldwide thanks to their high quality of taste. Switzerland is also renowned as the country with the highest chocolate consumption per capita. Today, many popular brands can be found even in the supermarket. Are you curious about what makes the chocolates special? And which non-destructive technique (NDT) can be employed to measure them?

Measuring Photo-Enhanced Ionic Conductivity

Dino holding the MFIA and the April issue of Nature Materials

This blog post summarizes the latest academic project of Dino, our new Application Scientist Impedance Analysis. He investigated materials for high-temperature fuel cells in Fukuoka, Japan and the results made it to the front cover of Nature Materials. Learn how light can be used to increase the ionic conductivity of standard electrolyte materials for solid oxide fuel cells, and how to measure this effect using the MFIA Impedance Analyzer.

Probing Local Magnetic Field Patterns - Q&A

Probing Local Magentic Field Patterns

For this webinar we teamed up with Prof. Martino Poggio , whose work focuses on understanding the physics of materials and phenomena that is strongly dependent on the local conditions, be it by impurities or through the design through local probing of magnetic fields coming from currents and magnetization. Several...

Nanostructure Transport Characterization - Q&A

25.05.2020

Transport Characterization

Thank you to everyone who attended the "Nanostructure transport characterization" Webinar. It was my first webinar and it was an amazing experience for the whole team. We received a lot of questions and in this post I will answer most of them by grouping them into four categories: Measurement tools...
