Metal oxide thin films are essential layers and interfaces in various optoelectronic applications including solar cells, smart windows, displays and semiconductor devices. Tuning their properties (resistivity, transmittance, carrier concentration and mobility) is a deposition-process dependent task that also includes detailed thin film characterization by various methods (SEM, XRD, XPS, Auger and Raman, just to mention the main ones). If you are interested in thin film fabrication by physical vapor deposition methods we are offering a unique opportunity that combines access to cleanroom facilities for deposition and characterization with access to plasma laboratory, where aspects of plasma induced or assisted sputtering are investigated by specific methods such as: mass spectrometry, optical emission and probes.
You will be based at DTU Nanolab, where we conduct cross-disciplinary research in nanofabrication and characterization in collaboration with several DTU departments. The Plasma Aided Nanotechnology research group hosts the plasma laboratory and is actively involved in deposition of functional thin films for various applications, including transparent conducting oxides for solar cells and smart windows, electrolytes for all-solid-state batteries, interface layers for fuel cells and functional membranes.
Responsibilities and qualifications
The overall ambition of this PhD project is to understand the growth mechanism of metal oxide thin films by magnetron plasma sputtering, including various modes of operation (direct current, pulsed, mid-frequency, radio frequency and high power impulse magnetron sputtering) in configurations with flat and rotatable targets. This understanding will be propagated as to improve the conventional sputtering methods with respect to setup design and process receipt.
Your main contribution will be deposition and characterisation of thin films in direct interaction with plasma diagnostics. The primary tasks will be to:
- plan and execute experimental research
- deposit thin films by magnetron plasma sputtering for various process parameters
- measure the optoelectronic properties (resistivity, transmittance, carrier concentration, mobility)
- perform analytical characterization
- integrate the functional thin films in optoelectronic devices in direct collaboration with scientific collaborators
- analyse the results and write scientific reports and papers
- contribute as teaching assistant at DTU Nanolab and supervise BSc and MSc student projects
You must have a two-year master’s degree (120 ECTS points) in micro- or nanoengineering, physics, mechanical or electric engineering or a similar degree with an academic level equivalent to a two-year master’s degree. Experience with cleanroom fabrication is an advantage. You are expected to have a high level of interest in nanofabrication and be able to interact with researchers in a very interdisciplinary environment. A high-grade average and excellent English language skills are decisive to be considered for the scholarship.
