My name is Karl Jonas Riisnaes and I am a researcher at the centre for doctoral training in metamaterials at the University of Exeter. My masters-degree (Graduated 2015) was in electronics and electrical engineering at University of Glasgow.

I am part of a cohort of researchers - PhDs and post-docs - all working within related fields. The cohort ethos is very much centered on exchanging ideas and collaborations. As a result of this, the first year of the PhD contains a lot of training, both theoretically and practically, to enable all researchers to exchange ideas and topics effectively.

My research is concerned with a crystal family known as Perovskites which show great potential for a wide range of optoelectronic applications. My research is currently focused on better understanding the physical properties of organic-inorganic perovskites by carrying out characterisation of high quality perovskite crystals supplied to me by my collaborators. My aim is to use this initial research to aid me in the development of perovskites based electrically induced lasers. The final goal of the project will be to demonstrate an electrically driven hybrid graphene and perovskite laser by harvesting the unique synergy of state-of-the-art developments on atomically thin light emitting diodes and lasers, and the novel atomically thin electrically conductive graphene materials.

Your support makes a considerable difference for me economically which will enable me to devote more time and resources on the research. I feel excited about keeping you up to date on my research and look forward to meeting you in person.

Kind regards

Jonas
