Watching a GaN Transistor Switch: Real-Time Nanoscale Strain and Heat Dynamics
C. Corley-Wiciak, N. T. Sammler, B. Butej +16
Digital and energy technologies depend on microelectromechanical and power electronic components whose performance is critically impacted by rapid, cyclic deformations. Real-time i…
Subgrain-resolved Analysis of Degradation in Cu Metallization via Scanning 3DXRD and Thermomechanical Modeling
Nikhil Prabhu, Laura Neumann, Michael Reisinger +7
Metallization layers play a key role in the performance and reliability of modern power semiconductor devices. During short-circuit events, rapid heating of power metallization lay…
TrueEBSD in MTEX: automatic image matching for correlative microscopy applications
Vivian Tong, Stefan Olovsjö, Rachid M'Saoubi +3
TrueEBSD is an open-source MATLAB program for image alignment and spatial distortion correction of images and electron backscatter diffraction (EBSD) maps. We have re-implemented T…
Interface Energy and Phase Transformations: A Comparative Analysis of Cahn-Hilliard and CALPHAD-based Models in Ternary Substitutional Alloys
Wolfgang Flachberger, Thomas Antretter, Swaroop Gaddikere-Nagaraja +3
There are various methods for modeling phase transformations in materials science, including general classes of phase-field methods and reactive diffusion methodologies, which most…
First principles study on the segregation of metallic solutes and non-metallic impurities in Cu grain boundary
Vasileios Fotopoulos, Jack Strand, Manuel Petersmann +1
Metallic dopants have the potential to increase the mechanical strength of polycrystalline metals. These elements are expected to aggregate in regions of lower coordination, such a…
