Cathodoluminescence (CL) spectroscopy consists in studying the low energy (~0.1-10 eV) photons emitted from a semiconductor material upon its excitation with an electron beam. It has several traits making it unique compared to alternative spectroscopy techniques, such as a nm-scale resolution, fast imaging capability, excitation depth control, and independence of materials excitation energy.
These notions will be discussed and applied to a selection of examples of Nitrides-based devices such as v-pits engineering and point defects density in LEDs, microLEDs and device reliability in high electron-mobility transistors.
The selected applications will be used to convey Attolight's approach to make CL quantitative, consistent and repeatable, both in normal and picosecond time-resolved mode.
Christian Monachon is Head of Applications and Product Manager of Analytical tools at Attolight AG, which he joined in 2016. He uses the broad scientific experience he acquired at EPFL (Switzerland), Northwestern University (Illinois) and the University of California at Berkeley, to creatively solve customers' demands and turn them into products and features on Attolight's cathodoluminescence spectroscopy-oriented electron microscopes. He also co-advises a PhD student on a Swiss national science foundation project and coordinates Attolight's effort in UltimateGaN a European project aiming at the improvement of GaN-based power devices.
Special Note
We were originally scheduled to deliver this presentation at UCSB as a Nitrides Seminar on April 2nd. We hope to deliver this presentation in person in the near future - we are offering this webinar for an advanced look at our technology.
We hope you and your family are safe during this difficult time.
