Dr. Bernhard C. Bayer (Universität Wien, Physik): "Realising scalable growth and integration of low-dimensional nanomaterials"

Two-dimensional (2D) and one-dimensional (1D) nanomaterials such as graphene, hexagonal Boron-Nitride, transition metal dichalcogenides and carbon nanotubes are set to revolutionize trans-parent and flexible electronics and add unprecedented efficiency to energy harvesting/storage devices.
There are however two current key roadblocks for real-world low-dimensional nanomaterials applications: First is the need to develop industrially-scalable synthesis methods for low-dimensional nanomaterials with controlled properties, where the most promising synthesis technique is chemical vapour deposition (CVD). Second, actual real-world device applications will require all these novel low-dimensional materials to integrate seamlessly with a wide range of other established functional (nano-)materials such as metals, metal-oxides or organic semiconductors.
Understanding and control of the resulting structural, chemical and electronic interaction phenomena remains however elusive. In this talk, I will describe how both issues are addressed by combining parametric CVD and integration process development with advanced nanomaterials characterization: A combination of in-situ techniques (such as X-ray photoelectron spectroscopy and X-ray diffractometry during scalable CVD conditions and realistic processing) with atomically-resolved scanning transmission electron microscopy thereby provides the critically required physical and mechanistic insights towards rational 2D and 1D growth and integration process design.
