Webinars

In this webinar, Kıvanç looks at the best ways to use time- and frequency-domain tools to characterize sensing devices. In particular, he shows how to set up feedback loops for sensor control without the need for time-consuming and expensive application-specific integrated circuitry (ASIC) development. A detailed blog post accompanies this webinar.

This session features a talk by Prof. Brice Gautier (INSA Lyon) and a tutorial by Dr. Romain Stomp (Zurich Instruments).
In this talk, Brice reviews the technical aspects enabling the use of PFM for domain imaging, hysteresis loops and domain engineering in the DFRT mode. He points out the most common artefacts and shows how experimental conditions influence measured properties. Brice also provides examples of ferroelectric domain control by means of an electric field or mechanical stress. Following the talk, Romain's tutorial looks into the DFRT method and feedback optimization.

This session features a talk by Mr. Valentin Aubriet (CEA-LETI Grenoble) and a tutorial by Dr. Mehdi Alem (Zurich Instruments).
In this talk, Valentin presents a setup for heterodyne Kelvin Probe Force Microscopy (h-KPFM) – featuring the HF2LI Lock-in Amplifier – under frequency-modulated and wavelength-dependent illumination. He then shows how to characterize silicon interfaces embedded under different types of oxides. In the tutorial following this talk, Mehdi discusses electrical pump-probe methods with arbitrary waveform generators.
