Nanowires are finding uses in optoelectronics and photovoltaics, and they are key materials in novel technologies such as quantum computing. The underlying growth processes to create the structures from silicon or III-V materials is a complex interplay of many nanoscale processes.

This project is based on our previous experience with silicon nanowire growth on microcantilevers inside a transmission electron microscope (TEM) to directly view and explore the growth processes as they take place. We will be using the recently installed and unique TEM system combining Metalorganic Vapour Phase Epitaxy (MOVPE) with live high-resolution imaging at Lund University.

You will develop, fabricate and use microfabricated heater systems at DTU to study the processes of III-V nanowire growth with MOVPE-TEM, thereby creating nanowire devices while imaging the process in the TEM. Afterwards, you will do further optical and electrical characterization of the created devices at DTU.

Aiming to create a better foundation for nanowire III-V optoelectronic devices, this PhD project will combine world-leading competences at Lund University, DTU Fotonik and DTU Nanotech in a push for unprecedented characterization, control and understanding of the complex III-V MOVPE growth processes.

Responsibilities and tasks
Your research will include a combination of the following:
  • Design, fabrication and test of microcantilever heater systems in the DTU Danchip cleanroom
  • In-situ TEM with MOVPE nanowire growth at Lund University in collaboration with the group of Kimberly Thelander
  • Nanowire characterization with optical and electrical methods at DTU and Lund University
  • Modelling and analysis to understand the obtained results and how they can be used to develop new III-V device functionality
Ideally, you already have experience with some of the skills listed above.

Your PhD project will:
  • Be situated within a collaboration between two universities, including frequent visits to work at Lund University. You must be open to travelling and working with international colleagues.
  • Cover several skills within fabrication, growth, TEM and characterization. The project will push beyond state-of-the-art techniques for in-situ TEM measurement capabilities, and as such, it will require a dedicated and curious analytical mindset.
  • Probe complex processes where you will develop new understandings within different topics. You will combine input from multiple collaborators and increase your overview of the problems at hand.
Candidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in engineering.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.
