Perovskites and piezoelectrics: top research at our next Ask an Expert webinar
Find out more about what our experts will be discussing in our April 2024 Ask an Expert webinar.
Some of our best ideas come from talking to you – our community. So, we’re delighted to announce that Ask an Expert is returning! On April 25, 2024, at 16:30 CET, another round of great conversations between Malvern Panalytical experts and our customers awaits.
Already excited for the return of Ask an Expert? Register here to reserve your place!
Ask an Expert is the perfect opportunity to find out more about the great discoveries being made with the help of Malvern Panalytical instruments. You’ll learn how to get the most out of your instrument and discover how leaders in their fields are using theirs to advance their research.
In our April 2024 webinar, we’ll be joined by Damian Wlodarczyk, PhD student and Chemical Technician at the Institute of Physics, Polish Academy of Sciences, and Shardul Pandit, Senior Engineer in MEMS Technology Development at Infineon Technologies.
Damian and Shardul were shortlisted for the Malvern Panalytical Scientific Award in 2023. The Scientific Award committee shortlists the top ten scientific papers and an overall winner out of hundreds of submissions. In Ask an Expert, Damian and Shardul will present the work that earned them a coveted place on the Scientific Award shortlist!
Talking double perovskites with Damian Wlodarczyk
Damian Wlodarczyk will talk about his research on two novel, rock-salt-type minerals – double perovskites – and their luminescent properties when exposed to near-ultraviolet (NUV) light. Double perovskites are named after the Russian mineralogist Lev Perovski. When they host cerium (Ce), their mineral structure is modified, prompting new observations of their energy or charge transfer in low temperatures and how their phase transitions are affected by temperature and pressure stimuli. Damian will also discuss the variety of analytical techniques used in his research.
In particular, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) have helped to reveal how the atoms in these cerium-hosting materials are arranged, which is an influential factor in how they emit light when exposed to NUV light. It promises to be a tantalizing glimpse into the more efficient photovoltaic materials of the future!
Piezoelectric progress with Shardul Pandit
Shardul Pandit will present his research on how a seed layer of aluminium nitride (AIN) can enhance the piezoelectric performance of yttrium alloyed aluminum nitride (Y0.15Al0.85N) thin film layers. Recent studies have suggested that yttrium is a ‘promising and less expensive’ alternative to scandium (Sc) in thin films for microelectromechanical systems. For the first time, Shardul has found improvements in piezoelectric performance when the AIN seed layer is present impacting strongly on graining, crystalline quality, and piezoelectric properties of Y0.15Al0.85N thin films.
In addition, Shardul for the first time, reported the crystalline stability of Y0.15Al0.85N layers in a pure oxygen environment up to 1200 °C, demonstrating a high oxygen resistance up to 800 °C. In our webinar, Shardul will share more about the latest analytical techniques that led to his findings and what he discovered about the behavior of piezoelectric materials at the microscopic level.
It promises to be a knowledge-rich and highly informative Ask an Expert session, with cutting-edge research up for discussion with the people who worked on it. We’d love to have you join us!
The webinar takes place on April 25, 2024, at 16:30 CET.
