Dr. Kagiso Loeto receives Humboldt Research Fellowship#
We are delighted to announce that PDI Postdoc Kagiso Loeto has been awarded a prestigious Humboldt Research Fellowship from the Alexander von Humboldt Foundation, which recognizes and supports outstanding researchers with exceptional qualifications.
Through this fellowship, Dr. Loeto will lead a new research initiative to investigate fundamental phenomena limiting the internal quantum efficiency of deep-ultraviolet light-emitting diodes (DUV LEDs). This pioneering work will harness PDI’s recently installed time-resolved cathodoluminescence system to push the boundaries of our understanding of these critical devices. For the first time, this study aims to directly image non-radiative point defects—major contributors to efficiency losses in DUV LEDs—using high-resolution cathodoluminescence imaging. By visualizing these defects, the research seeks to uncover their impact on device performance, paving the way for strategies to mitigate efficiency losses and enhance the functionality of DUV LEDs.
Dr. Loeto shares, “This fellowship is an incredible opportunity to pursue cutting-edge research at PDI, providing the resources and environment to explore innovative approaches and contribute meaningful insights to the scientific community. Beyond the science, this award also acknowledges the potential impact of this work and allows me to grow both as a researcher and as part of a global community dedicated to advancing knowledge and technology.”
Congratulations, Kagiso, on this well-deserved recognition! We look forward to the discoveries this research will bring.
