Open Semester and Master Projects at the Laboratory for Nanoelectronics

We have projects for students interested in experimental or computational work, or a mixture of both. Topical areas range from device engineering, advanced characterization techniques, physics of materials, and chemical synthesis.  All projects are motivated by real world applications of new materials and systems: energy storage (e.g., batteries), energy generation (e.g., solar cells), optoelectronics devices (e.g. LEDs or lasers), transistor free memory, and thermoelectrics.


We are delighted to welcome students from a variety of departments (e.g., D-ITET, D-MAVT, D-MATL, D-PHYS, and D-CHEM) or interdisciplinary MSc programs.

Lithium Plating in Commercial Pouch Cells

Under certain conditions, lithium ion batteries exhibit lithium metallic plating on the anode, so called plating. The goal of this master thesis is to study the impact of the assembly technique and form factor of the battery cell on the onset and severity of plating, using a combination of optical microscopy, scanning electron microscope (SEM) imaging, and cyclic voltammetry.

Required background/skills: It is preferable if you already have previous experience working in a laboratory.

Design and implementation of a spraying device for production of battery materials 

In many high temperature processing steps, a vapor phase is created to improve material quality. Your aim is to design a setup able to spray liquids into a hot oven, where they vaporize. In a second step, you will implement this setup to battery electrode materials and characterize the results using electrochemical and surface characterization methods.

Required background/skills: Background in mechanical or electrical engineering is desirable. Some experience in CAD is beneficial.

Electrolyte-separator interactions in lithium ion batteries (semester/master thesis)

The influence of battery separators on the electrolyte conductivity and ion transport in lithium ion batteries is poorly understood. Recently we experimentally showed that different surface functionalizations strongly influence the separator performance. The aim of this project to model these interactions in a 3D finite element simulation with COMSOL and Matlab.

Required Background/Skills: Some experience in programming (e.g., Matlab) is desirable.

Phase transitions in colloidal nanocrystals (semester/master thesis)

Temperature-dependent X-ray diffraction and electrical measurements of colloidal nanocrystals, which belong to the family of phase change materials (PCMs). Assessment of nanocrystals for transistor-free memory applications, based on measurements.

Required Background/Skills: background in physics or electrical engineering.

Defect-induced properties of phase change materials (semester/master thesis)

Ab-initio (VASP) and/or tight binding (OMEN) calculations of rock salt structures with variable defect concentration and defect ordering. Assessment of amorphous-to-crystalline transition temperature and resistivity contrast for calculated structures.

Required Background/Skills: background in physics or electrical engineering, experience in simulations (Unix, Matlab, C).
