Quality of MX2 materials

Leuven | More than two weeks ago

How can we improve the quality of 2D materials to foresee their integration in new technologies?

In depth investigation of the transfer process of 2D compounds on the material quality.

 

The topic:

Two-dimensional (2D) materials are promising candidates for integration in future electronic, (bio)sensing, photonic and even energy applications thanks to their numerous exciting physical properties like high thermal conductivity, flexibility, tunable light absorption, superconductivity, high mobility, etc. To foresee their integration in new technologies, two strategies are currently investigated by the community: direct growth and transfer, both presenting specific challenges to meet industry requirements, but also advantages. Our team focuses on the development of the transfer.

 

In the last years, we have developed a transfer process that can be adapted to the different 2D materials available at imec. However, to guarantee the delivery of high quality material for devices, the process needs optimisation. In particular, the interfaces of the delivered layer, top and bottom, is of the outmost importance because the surrounding can induce doping. Knowing that, we want to investigate the possibility of modifying their properties by controlling the interfaces and minimising the defects. Thus, we are looking at different substrate and different treatment of the layer.

 

What you will do:

The project is focused on the study of material quality. We want to understand better the chemical and physical effects generated during the transfer process. This is an experimental research topic which requires working most of the time in the clean room (wet bench and glove box). Activities include manipulation of chemicals to clean and prepare the samples, the realisation of physical characterisations: optical microscopy, AFM and photo-luminescence spectroscopy together with the analysis of the data. All the necessary training will be provided, and we will support you in the writing of your Master thesis.

 

The team:

Imec being international, fluent English is mandatory. The project is a collaboration with 2 teams the project will be under the supervision of both Dr. Marie-Emmanuelle Boulon and Dr. Clément Merckling. As a member of the team, you are expected to interact with your colleagues, communicate openly about your activities and result, participate to our group meetings.
