Drive level capacitance profiling (DLCP) is a powerful technique to accurately determine the charge carrier density in semiconductors when deep level states are present. It is often considered an improvement over the widely applied characterization technique known as capacitance-voltage (C-V) profiling...

In electrochemistry, the characteristics of a given process can be assessed by electrochemical impedance spectroscopy (EIS). A semicircle in the Nyquist plot usually corresponds to electrochemical processes that can be modelled as a parallel connection of a resistor (R) and a capacitor (C). The diameter of the semicircle provides the value of R, while the associated time constant (also known as relaxation time) is given by RC...

The MFIA is a high-precision impedance analyzer. It measures voltage, current and phase to calculate impedance. As is the case for most impedance analyzers, the measurement circuit is designed so that the device under test (DUT) is operated under floating conditions, which means that none of the terminals of the DUT is connected to the ground...

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?

This blog post accompanies the webinar "Superconducting Qubit Characterization", which introduced the basic physics of transmon qubits as well as the tools and methods required to tune them up. The webinar included a live Q&A session, but due to time constraints, not all of the viewers' questions could be answered within the duration of the session. Below, we address the technical questions asked during the webinar...

This blog post provides the answers to the questions asked by the audience during the webinar "Boost Your Optical Signal Detection with Lock-in Amplifiers and Boxcar Averagers”, and points to other helpful resources. 

An arbitrary waveform generator (AWG) can generate pulses with a timing resolution much finer than its sampling period. Users are often unaware of this capability, yet it enables highly precise timing control in application use cases such as NV center dynamical decoupling, flux pulse width control, AWG channel deskew, and IQ mixer calibration...

Were you ever curious about how the double-superheterodyne frequency conversion compares with IQ mixing when tested on real qubits? This blog post introduces such a comparison published in a recent preprint paper by the ETH QuDev lab. One of its main results hints at double-superheterodyne enabling a higher gate fidelity and lower state leakage rate than a standard IQ mixing approach!

Among sensing applications, mass measurements have received a lot of attention with the shrinking of devices and the ability to detect individual particles. We have witnessed the shift from macroscopic devices such as the micro-balance to micrometer-size resonator devices and, now, to 2D or 1D materials with exquisite resolution down to a single proton's mass...

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.

In this blog post, we will have a look at how an EIS measurement of a standard 18650 cell can be carried out using an MFIA Impedance Analyzer, and how important a short-load compensation routine is to improve our measurement accuracy.

This blog post accompanies the online launch event of the GHFLI and SHFLI Lock-in Amplifiers, the trailblazers that bring state-of-the-art signal generation, analysis, and control to microwaves. Watch the recording and read the transcript of the Q&A to learn about the innovations brought by these new instruments and how they can help researchers and engineers.

Does your application require multiple AWG channels with precise and stable timing synchronization? In this blog post, we will show how to achieve this with the HDAWG Arbitrary Waveform Generator for setup sizes ranging from few channels up to 144. We demonstrate 3 methods suitable for different use cases.

Lock-in amplifiers are extremely versatile and used in a plethora of applications ranging from optics and photonics, nanotechnology, spm, and sensing, among others. In this blog, you will learn how to use the MFLI Lock-in Amplifier to carefully assess the experimental conditions and prepare your setup for the best measurement outcome.
