A new paper on correlative electron and super-resolution light microscopy has been published in Scientific Reports by scientists from ETH Zurich. The authors present an imaging workflow that allows obtaining correlative super-resolution light and scanning electron microscopy images in an easy and fast way. 

If you always wanted to learn what cathodoluminescence and CL imaging are, our recent webinar Introduction to cathodoluminescence imaging is a perfect way to start. Presented by our application specialist Sangeetha Hari, the webinar describes what cathodoluminescence is, how it is generated and how it can be applied in different fields.

For those of you who wanted to join the upcoming workshop Cathodoluminescence for photovoltaics in Berlin and couldn't, we are excited to announce that you can join a webinar dedicated to the same topic, which will take place on the 28th of November, only one week after the webinar.

Delmic has been growing in 2019 and even more talented people have joined the company. Take a look at the most recent photos of our office and team to see who works at Delmic. 

A new paper was published in Nanoscale by researchers from AMOLF and DIFFER. The research focuses on tunable plasmonic HfN nanoparticles and arrays and demonstrates the possibilities for development and fabrication of such nanostructures. 

In the past year we have delivered and installed quite a few cathodoluminescence systems all over the world. We are proud to share with you a few notable installations of 2018 and 2019!

In the past few months we have covered various application fields in which cathodoluminescence can be successfully used. This time we decided to prepare a special edition webinar, which will cover the basic principles of CL. We are excited to invite you to a webinar "Introduction to cathodoluminescence imaging". 

Our invited speaker at the upcoming workshop in Berlin, David Lindgren, PhD, has a lot to share about his expertise in characterizing the optical properties of semiconductors. Delmic talked with him to give you a sneak peek of his presentation on the 21st of November. 

David has worked as a senior engineer at Sol Voltaics, a start-up which produced solar cells out of nanowires with a new technique called Aerotaxy. His PhD was dedicated to optical characterization of III-V semiconductors for different components like LEDs and solar cells. It allowed him to expertly manage cathodoluminescence and photoluminescence systems and perform fundamental research looking at impurities of materials and defects that could be related to malfunction of components.

If you couldn't join our workshop Analytical SEM for Geology in January, which was organised together by Delmic, Bruker, Hitachi and University of Oslo, you now have a chance to watch all the presentations online. We invite you to watch the recording of the webinar, which consists of two parts: Part I is dedicated to SEM combined with X-ray microanalysis (EDS) technique, which is great for understanding morphology and microstructure of materials. You can access it here.

While using cathodoluminescence imaging to study various materials can be extremely insightful, the spatial extent of the electron beam interaction with the material is not always clear. This is important if one is seeking to study particular features in a material. Moreover, by varying the electron energy it is possible to access various depths and obtain (coarse) 3D information.
