Background and activities

Research

I'm currently a PhD student in the project 'In-situ studies of highly conductive bonded interfaces between aluminium and copper at the nanoscale' (In-SANE), which is a multidisciplinary collaboration between IFY and MTP at NTNU. We aim to develop techniques, tools and procedures for microjoining of Al/Cu components in FIB, using welding methods similar to 'hybrid metal extrusion & bonding' (HYB). The objective is to downscale the welding process to scales relevant to electronic packaging at the nano-scale. My role is to participate in the above, in addition to perform detailed characterisation of the chemical composition and the atomic struture along the interface of the joint primarily using advanced 'transmission electron miscroscopy' (TEM) techniques.

Background

My background is in natural science with teacher education, and I completed my degree in materials physics at NTNU Trondheim at the TEM Gemini Centre. I was then characterising intermediate band solar cell (IBSC) materials using TEM. My main supervisor was then (and is now) Professor Randi Holmestad.
