I am an inorganic chemist with many interests, ranging from crystal growth to experimental synthesis. The core foundation is within deposition of solid materials by sequential gas-to-solid reactions, such as the atomic layer deposition (ALD) or molecular layer deposition (MLD) approach. We build the materials as crystalline or amorphous, resulting in a range of different textures, utilizing crystal growth principles.

Our thin film activities at UiO began in 1998 with the aim of controlling deposition of complex oxides by ALD. This led to controlled deposition of many different complex perovskites, spinels and other structure types. We have developed a model for better control of deposited stoichiometry in the multi-parameter space related to complex oxides.

The MLD activities began in 2004 with formation of metal hydriquinones, and later its carboxylic acid analogues. It is presently expanded to numerous other heterofunctional linkers where the major effort is within exploring new areas of applications, such as biocompatibility.

The ALD technique, with its conformal coverage, will most likely be a central part of the new technology of solid state batteries. We began exploring deposition of Li-containing materials in 2009, targeting battery applications, currently including both cathodes, electrolytes and anodes.

The efforts in exploratory synthesis has resulted in numerous different thin film reactor designs, suitable for small to large substrates, including powder and porous materials. Currently including 10 ALD reactors with suitable characterisation infrastructure. A key element for achieving this is suitable types of precursor delivery systems. All home made, thanks to open minded local workshop.  

I have also found much joy with public outreach activities and are currently running a yearly camp teaching nanotechnology to high school students.

A more thorough description of the thin film activities are given at the NAFUMA - thin film pages.
