Award

This research focuses on creating a groundbreaking transmission electron microscopy (TEM) in-situ specimen holder that allows for high-voltage biasing experiments—up to 1000V—while enabling real-time imaging of nano-scale electronic components. This innovative tool is essential for advancing the development of next-genera􀆟on high-voltage power converters, such as Gallium Nitride (GaN) JFETs. Currently, progress is hindered by insufficient observation methods to investigate critical factors like failure mechanisms, defect dynamics, and structural stability during device operation. By utilizing this in-situ TEM holder, researchers aim to dissect failure modes and their underlying causes to enhance the performance of these power converters. Improvements in this area are pivotal for supporting advancements in renewable energy integration, electric vehicles, power transmission and distribution, medical equipment, and consumer electronics. The project is structured in two phases: Phase I focuses on the development, construction, and testing of the high-voltage TEM holder, while Phase II is dedicated to its commercialization through Hummingbird Scientific’s product line. This research promises to pave the way for significant technological advancements, benefiting numerous industries and the public at large.
