Webinar Summary – Boost Your SPM Applications: From Kelvin Probe to Time-Resolved Measurements

on 19.10.2020 at 17:03 by Romain Stomp
Following up on the webinar dedicated to Kelvin Probe Force Microscopy (KPFM) techniques, I’d like to post a short summary in this blog as well as answers to most questions raised during this event. The recording of this webinar can […]

Meeting SPM Users Virtually

on 16.05.2020 at 06:32 by Romain Stomp
The 4th SPM User Meeting that was originally planned to occur in April in Lyon, was rescheduled to 2021 due to the Covid-19 situation. We therefore found inventive ways to stay connected with our community, in a virtual manner, while […]

DFRT revisited: from feedback optimization to full DAQ acquisition

on 18.02.2020 at 18:17 by Romain Stomp
The Data Acquisition module (DAQ) in LabOne has been addressed in 2 recent blog posts: A deep dive into data acquisition with the DAQ tool & Choose the right tool to acquire lock-in data. One other great application area for […]

Resonance enhancement: a tale of two data analysis methods

on 17.09.2019 at 11:37 by Romain Stomp
The Benefit and Challenge of using Resonance Enhancement Resonance enhancement technique is the fastlane toward raising signal well above the noise floor to increase signal-to-noise ratio (SNR) and dynamical range. Such an approach is common for Scanning Probe Microscopy (SPM) […]

SPM community brought together in Zurich

on 03.06.2019 at 10:16 by Romain Stomp
Zurich Instruments User Meeting
“Jamais 2 sans 3,” as the French say, where number three worked as a charm. For this 3rd SPM User Meeting, we were able to host the meeting in our home city and brought together more users than ever before […]

Formation sur les techniques KFM à Grenoble

on 29.11.2017 at 18:17 by Romain Stomp
Pour la seconde année consécutive, le réseau RéMiSoL (voir ci-dessous), avec le soutien du CEA LETI, de l’IEMN et de partenaires industriels (NanoAndMore, Zurich Instruments), a proposé une action nationale de formation (ANF) CNRS le 7 et 8 Novembre sur […]

How to measure PLL/PID bandwidth under real experimental conditions

on 14.11.2017 at 10:52 by Romain Stomp
With the merging of PLL and PID tab in LabOne for MFLI and UHFLI, the PID Advisor section is now identical for both type of feedback loops and various system models can be tested. After all, a Phase Locked-Loop (PLL) […]

SPM Users’ Meeting in Mainz

on 21.07.2017 at 15:08 by Romain Stomp
It was an honor and privilege to host our first SPM Users’ Meeting in Mainz this year, in the group of Prof. Angelika Kuehnle. This 2-day gathering was a time for intense knowledge sharing among Zurich Instruments’ Users with invited […]

Fast auto-approach with MFLI Threshold Unit to control stepper motor

on 22.02.2017 at 11:19 by Romain Stomp
In many applications where the distance between two objects need to be reduced to a predefined gap, the ability to control a stepper motor with clear stop conditions from different sensors is of high practical interest. Such functionality can be […]

Compensating delay-induced phase shifts for high-frequency resonators

on 20.02.2017 at 14:31 by Romain Stomp
Phase-Locked Loop (PLL) or other PID controllers on nano-mechanical resonators rely on clean phase signals that exhibit large slope, or significant phase shift, around the resonance frequency. For really high-frequency NEMS and opto-mechanical systems above a few tens or hundreds […]
