Due to the ongoing miniaturization of modern semiconductor devices towards low dimensionality and nanometric size, interfaces between different materials are becoming increasingly important for the functionality and performance of these devices. Interfaces are three-dimensional (3D) objects with a topographic character, often described by crystallographically defined extended terraces and steps, along with a transition region formed by atom interdiffusion.
The detailed characterization of such interfaces is frequently performed by atomic-resolution (scanning) transmission electron microscopy (S-TEM) studies, which can have limited validity due to the projection property of the 2D images.
We have recently introduced the advanced method of electron tomography , which allows for reconstructing 3D structure information of semiconductor interfaces and independently determining both morphological roughness and chemical intermixing. For this purpose, a tilt series of STEM images is created, which determines the 3D structure through computer-aided reconstruction algorithms. The spatial resolution of this 3D reconstruction is directly related to the transmitted material thickness, including the interface, and depends on the type of material and the interaction between electron and matter.
The master thesis should address experimental investigations on the 3D resolution of the interface tomography by examining the interplay between beam divergence (a geometric effect of the converged STEM probe) and beam broadening (an unavoidable broadening due to multiple elastic scattering). For these investigations, silicon-based interfaces with well-defined morphological characteristics are available as a model system, prepared by focused ion beam technique into customized tomography needles with different thicknesses.
Responsibilities:
- Introduction to methods of scanning transmission electron microscopy and tomography
- Performing tilt series in a high-end Cs-corrected STEM on Si-based interfaces
- Conducting the 3D reconstruction
- Discussing limits of 3D spatial resolution
Minimum Requirements:
- BSc in physics, chemistry, or materials science
- Basic knowledge in TEM beneficial
- Experience in programming
- Motivation to work in a team
- Enrolled in a University inside the EU
