Low-Frequency DLTS of Perovskite Solar Cells with the MFIA

on 29.06.2021 at 00:19 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 defects in semiconductors. The technique involves measuring capacitance transients at different temperatures, typically at 1 MHz. However, DLTS can also […]

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 […]

Take Your Dielectric Measurements to the Liquid State

on 25.05.2021 at 14:06 by Meng on Blog of Meng Li
Liquid dielectrics are dielectric materials in a liquid state and are widely used in electrical insulation as well as cooling. Nonetheless, their fluidity also makes accurate dielectric measurements a challenge. In a previous blog post, we saw how to measure […]

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 […]

Optimize the SNR of a laser-scanning microscope with lock-in amplifiers

on 25.05.2021 at 10:39 by claudius on Blog of Claudius Riek
Improving the signal-to-noise ratio (SNR) is desirable for every laser-scanning microscopy application. It enables the observation of smaller changes or faster processes in a sample. This blog post explains how using a lock-in amplifier or a boxcar averager can boost the SNR […]

Randomized benchmarking in seconds

Randomized benchmarking (RB) is a widely used tool in quantum information science to determine qubit fidelity and to characterize individual qubit gates. It is also an excellent example of a quantum experiment with advanced requirements on the control hardware and […]

Comparison of Liquid Conductivity Probes with the MFIA

on 29.04.2021 at 10:22 by Meng on Blog of Meng Li
In the previous blog post, I have described how to use the MFIA impedance analyzer to measure the electrochemical impedance spectrum (EIS) of a liquid sample, and to derive the conductivity with EIS modeling. The post presented a 5-element equivalent […]

Customising the Output Data Format of Impedance Sweeps

on 16.04.2021 at 12:05 by Tim Ashworth on Blog of Tim Ashworth
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 […]

Capturing transients with Zurich Instruments Toolkit: Programing your instruments was never that easy

on 07.04.2021 at 09:27 by Meng on Blog of Meng Li
In many applications, Zurich Instruments lock-in amplifiers and impedance analyzers are integrated into a larger measurement system. Having an application programable interface (API) to obtain necessary information from the instruments is of great importance in such cases. Thanks to the […]

Practical active qubit reset

on 05.03.2021 at 15:48 by andrea on Blog of Andrea Corna
Practical active qubit reset When working with qubits, it’s essential to have a reliable state preparation. The easiest method for superconductive qubits is to passively wait for the qubit to decay into its ground state, but it’s slow and has […]
