Effect of extended defects on AlGaN QDs for electron-pumped UV-emitters
Jesus Cañas, Névine Rochat, Adeline Grenier +8
We study the origin of bimodal emission in AlGaN/AlN QD superlattices displaying high internal quantum efficiency (around 50%) in the 230-300 nm spectral range. The secondary emiss…
The influence of illumination conditions in the measurement of built-in electric field at p-n junctions by 4D-STEM
Bruno C da Silva, Zahra S Momtaz, Lucas Bruas +4
Momentum resolved 4D-STEM, also called center of mass (CoM) analysis, has been used to measure the long range built-in electric field of a silicon p-n junction. The effect of diffe…
Assessment of active dopants and p-n junction abruptness using in-situ biased 4D-STEM
Bruno C. da Silva, Zahra S. Momtaz, Eva Monroy +4
A key issue in the development of high-performance semiconductor devices is the ability to properly measure active dopants at the nanometer scale. 4D scanning transmission electron…
High-sensitivity mapping of magnetic induction fields with nanometer-scale resolution: comparison of off-axis electron holography and pixelated differential phase contrast
Victor Boureau, Michal Staňo, Jean-Luc Rouvière +3
We compare two transmission electron microscopy (TEM) based techniques that can provide highly spatially resolved quantitative measurements of magnetic induction fields at high sen…
