Three-dimensional imaging of oxygen dopant distribution in SrCuO by electron ptychography
Hongbin Yang, Jinkwon Kim, Desheng Ma +3
Oxygen dopants play a critical role in tuning the properties of cuprate superconductors, yet it is challenging to visualize them at the atomic scale. Here, we use multislice electr…
Detective quantum efficiency based comparison of HRTEM and ptychography phase imaging
Felix Bennemann, Angus I. Kirkland, David A. Muller +1
High-resolution transmission electron microscopy (HRTEM) is an important method for imaging beam sensitive materials often under cryo conditions. Electron ptychography in the scann…
3D Atomic-Scale Metrology of Strain Relaxation and Roughness in Gate-All-Around (GAA) Transistors via Electron Ptychography
Shake Karapetyan, Steven E. Zeltmann, Glen Wilk +3
To improve transistor density and electronic performance, next-generation semiconductor devices are adopting three-dimensional architectures and feature sizes down to the few-nm re…
PtyRAD: A High-performance and Flexible Ptychographic Reconstruction Framework with Automatic Differentiation
Chia-Hao Lee, Steven E. Zeltmann, Dasol Yoon +2
Electron ptychography has recently achieved unprecedented resolution, offering valuable insights across diverse material systems, including in three dimensions. However, high-quali…
