Melt growth and doping of bulk SrTiO3, Ga2O3 and In2O3

 

 

Overview of the research project:

In this project we prepare bulk single crystals of strontium titanate and other transparent semiconducting oxides with improved crystal properties. It is based on the land-standing experience and expertise in melt growth of oxide bulk crystals at high temperatures. The IKZ is continuously advancing and extending its growth technologies for novel and less matured bulk materials in the field. We are tackling problems of growth stability and reproducibility, diameter and length increase, doping, segregation, and dopant homogeneity, structural quality and defect formation, impact of growth conditions and annealing on crystal properties, as well as substrate and sample preparation.


Major accomplishments expected:

The IKZ will demonstrate unprecedented or otherwise unavailable crystals, substrates and samples of bulk oxide materials (e.g. SrTiO3, Ga2O3, In2O3) in regard to composition, structural quality, physical properties (e.g. crystallographic orientation, doping concentration, homogeneity), and size/diameter.

 

Collaboration with partners in the project:

The project provides research and development (based on funded collaboration or cost sharing) for Science Campus members to obtain samples for their research, and to perform joint research and development on the preparation and characterization of novel bulk oxide materials.
