DLTS User Meeting 2021 Q&A

on 19.07.2021 at 06:05 by Tim Ashworth on Blog of Tim Ashworth
Deep level transient spectroscopy (DLTS) is a powerful and commonly used technique to investigate the concentration and carrier binding energy of semiconductor defects by measuring capacitance transients at different temperatures. As such, it is a critical tool for the characterization of […]

How to characterize magnetic materials using lock-in amplifiers: A Zurich Instruments and Cryogenic webinar summary

on 15.07.2021 at 11:00 by Jelena on Blog of Jelena Trbovic
In this webinar we covered two basic magnetic characterization techniques, the vibrating sample magnetometry (VSM) and AC susceptibility where lock-in amplifiers are essential part of the measurement and the detection chain. We teamed up with Yury Bugoslavsky who is managing […]

Evaluate Interdigitated Electrode Sensors with the MFIA

on 16.06.2021 at 15:45 by Meng on Blog of Meng Li
In the previous blog posts, we demonstrated conductivity and permittivity measurements of liquids using an MFIA impedance analyzer. To reach the best accuracy, the measurements were carried out using immersion probes or dielectric fixtures with a precisely defined electrode area […]

Impedance Measurements with Small Amplitude Test Signals

on 03.06.2021 at 19:17 by Tim Ashworth on Blog of Tim Ashworth
When taking an impedance measurement, the test signal amplitude can often be a factor which needs to be minimised to avoid unnecessarily disturbing the sample under test. This blog post presents measurements showing how even small test signals of just […]

How to configure the DAQ module for image acquisition

on 25.05.2021 at 12:40 by kivanc on Blog of Kivanç Esat
Data synchronization is the key to acquiring images, and in this blog post I explain how to configure the LabOne Data Acquisition (DAQ) module for this purpose. Let’s start with two concrete scanning microscopy examples as depicted in Fig.1: Raman imaging microscopy and […]

This short blog post will show you how to customise the exported data of your impedance sweeps on the MFIA and MFLI with MF-IA option. The Sweeper Module of LabOne is an excellent tool to sweep frequency, amplitude or bias […]

Webinar summary with Q&A – Probing local magnetic field patterns

on 26.02.2021 at 15:04 by Jelena on Blog of Jelena Trbovic
In this webinar we teamed up with Prof Martino Poggio who’s work focuses on understanding the physics of materials and phenomena that is strongly dependent on the local conditions, be it by impurities or through the design through local probing […]

Content review – Lock-in detection

on 15.02.2021 at 15:20 by kivanc on Blog of Kivanç Esat
Test and measurement tasks often carry the challenge that sought for signals are buried in noise. The fundamental use of a lock-in amplifier is to recover these signals, but modern digital lock-in amplifiers can do much more than this. To help you take […]

Compensating Cables for Accurate Impedance Measurements

on 19.01.2021 at 10:45 by Tim Ashworth on Blog of Tim Ashworth
Measuring impedance accurately can be a challenge, especially when the device or material under test is located some distance away from the impedance analyzer at the end of cables. The phase delay and parasitic impedance of the cables can significantly […]

Measuring Dielectric Properties of Materials with Varying Thickness

on 30.09.2020 at 08:52 by Meng on Blog of Meng Li
Introduction A dielectric is traditionally defined as an electrical insulator, with very poor conductivity at DC [1]. However, because of its polarizability, charges can be stored in a dielectric material, typically in the format of dipoles, in the low and […]

Webinar Q&A- Impedance Analysis; Measuring Fast and Low

on 23.06.2020 at 08:01 by Tim Ashworth on Blog of Tim Ashworth
This blog post answers the many welcome questions from the audience during the recent webinar “Impedance Analysis; Measuring Fast and Low”. This webinar covered two distinct and equally important impedance measurement challenges. The first involves measuring the low equivalent series […]

How to reduce noise floor and improve SNR by employing cross-correlation techniques

on 19.05.2020 at 15:30 by Jithesh Srinivas on Blog of Jithesh Srinivas
Ultra-sensitive voltage measurements is a crucial requirement for applications such as quantum device characterization [1]. Weak signals become easily obscured by thermal noise, especially that coming from the measurement apparatus; this increases the noise floor [2] and determines a lower […]
