Webinars

Deep level transient spectroscopy (DLTS) is a critical tool for the characterization of semiconductors. In this second edition of the DLTS User Meeting, Zurich Instruments brought together members of the DLTS community, to foster knowledge exchange and to network through scientific talks on the study of defects in Sb2(SSe)3, and in metal halide perovskite solar cells. Detailed tutorials also covered the study of transients and data acquisition. To read the answers to the questions during the live event, take a look at this blog post. To discuss your DLTS challenge, get in touch with Dino Klotz or Meng Li.

Would you like to start impedance measurements, but don’t know how? Or do you already use impedance spectroscopy but would like to know more about theory and practice, while also learning some practical tips and tricks?

This webinar introduces the basics of impedance spectroscopy and related analysis, and gives practical hints to avoid common errors. It consists of a tutorial lecture followed by demonstrations showing how to configure a fault-free measurement and how to optimize your setup. This blog post offers a summary of the webinar and includes the presentation as well as the answers to the questions asked during the live event.

Quantum technologies progress towards useful applications at a tremendous pace, with different technological platforms and approaches being explored. As key enablers of control and measurement solutions for quantum computing applications, Zurich Instruments and Rohde & Schwarz brought together researchers in quantum technologies working in different areas and facing distinct challenges but share core competencies and important know-how.

In this video, Prof. Peter Grutter provides an overview of his current research aimed at developing ultrafast laser methods combined with AFM to gain a better understanding of charge dynamics at the molecular time and length scales. He then presents his most recent results on mechanically detecting single electrons for single-molecule spectroscopy. The outlook of his talk addresses plans to adapt these methods to elucidate the energetics of organic charge transfer systems as well as the quantum properties of single and coupled dopants in silicon. Following Prof. Grutter's talk, Application Scientist Romain Stomp illustrates how the discussed methods can be implemented with Zurich Instruments' rich toolbox. The answers to the questions asked during the live event are summarized in this blog post.

As the size of electronic devices goes down to few nanometers, interfaces become increasingly relevant and often dominate and interfere with a device's performance. Hybrid devices are a particularly good example, because they rely on interfacing materials with different physical properties to control superconductivity, spin or other carrier characteristics in the active parts of the device. The performance of these structures depends critically on their reliable fabrication and interface characterization. In this webinar, Jelena Trbovic and Heidi Potts take you from general interface considerations to nanodevice characterization with lock-in amplifiers: you learn how to set up low-noise measurements and how to characterize devices on ultrafast timescales using RF reflectometry. The answers to the questions asked during the live event are summarized in this blog post.

In this video, Jan, Tobias and Bruno present the SHFQC Qubit Controller and discuss how this instrument can help speed up system tune-up and complex algorithm execution. The presentation includes practical demonstrations showing how to use the SHFQC to control, read out and perform fast feedback on up to 6 superconducting qubits with a single instrument, as well as a discussion of how the SHFQC can be integrated into larger qubit control systems. The answers to the questions asked during the live event are summarized in this blog post.

In this webinar, Ed, Jim, Jelena and Clemens look at how lock-in amplifiers offer a prime way to probe and understand material properties relevant for qubit coherence while keeping measurement times and complexity to a minimum. They discuss the basic working principles of semi- and superconducting qubits and demonstrate how to characterize frequency and loss fluctuations in readout resonators, as also summarized in this blog post.

In this webinar, Kıvanç Esat is joined by Dr. Tomás Manzaneque García (TU Delft) to look into the best practices for the characterization of a sensor with lock-in amplifiers. Kıvanç and Tomás cover practical examples including mechanical micro-resonators and optomechanical systems, they show how to set up feedback controllers for maximal precision and review the existing trade-offs between open- and closed-loop operation. A summary of the answers to the questions asked during the live event can be found in this blog post.
