Chiral 1D edge states of the quantum anomalous Hall effect can be used as “optical fibers” for electrons. To gain a deeper understanding of their properties, the dispersion relation and the attenuation of edge excitations in the microwave regime can be investigated. In this blog post, we present measurements that were performed in the lab of Prof. Bocquillon using our SHFLI 8.5 GHz Lock-in Amplifier.

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.

Timing is extremely important to correlate the results from different experimental signals. In this blog post we will show how to work with timestamps from a Zurich Instruments lock-in amplifier when measuring multiple signals simultaneously.

The most beautiful measurement data is useless if it cannot be saved and analyzed. Choosing the data transfer rate from the instrument to the host computer wisely is important to capture the information of interest and avoid measurement artifacts. In this blog post, we will look at the data transfer concept of a Zurich Instruments lock-in amplifier in more detail and provide guidelines on how to choose it.

This blog post accompanies the webinar "Interfaces: How to make or break a nanodevice". In this webinar, we discussed the role of interfaces for nanodevices: why they are important, how they can destroy the properties of a nanodevice, and how you can characterize interfaces using different measurement techniques.
