We are conducting transdisciplinary research in the fields of nanoscience and nanotechnology
Quantum transport
We are working on nano-electronic devices in the quantum limit at ultra-low temperatures. By employing Dirac materials and novel van der Waals structures we are able to reveal new states of matter under extreme conditions.
Bio-nano interfaces
The complex structure of biological systems is a challenge for engineering devices. In this research thrust we are making use of 3D-nanoprinting to construct fundamentally new device architectures with unprecedented abilities.
Nanomaterials growth
Revolutions in device technology are based on revolutionary new materials. We are tackling this task by a host of atomic-layer-deposition (ALD) machines, enabling the deposition of a huge variety of material layers – also in 3D. This is complemented by state-of-the-art molecular beam epitaxy (MBE) supplying us with low-dimensional electronic designer materials.
Nanoscale devices and sensors
Quantum limited resolution entails great potential for device and sensor applications. We are working in close collaboration with industry groups on realizing prototypes. This spans from applied nanomechanics and nanoelectronics over to nanooptics and novel microwave sources.
Nanoscale magnetism
The long tradition in nanoscale magnetism at our Institute over the last decades, we are continuing by studying two-dimensional electronic systems, such as graphene, with magnetic quantum dots. These quantum dots are realized by thin layers of Cobalt defined by high-resolution electron beam lithography and a subsequent sputtering step.
Top down nanofabrication toolkit
The central challenge in nanoscale physics is that the growth and fabrication of given structures or components at given locations for given functions. We are conducting research on a new top down nanofabrication technique in which we can tailor morphology, shape, complexity, order, assembly mechanism, and crystallization that might facilitate the design of high-performance photonic, electronic, and electromechanical nanodevices.

Stem cell-derived neurons on nanowire array
NewsNanowire arrays interfaced with biological cells have been demonstrated to be potent tools for advanced applications such as sensing, stimulation, or drug delivery. This study published in Advanced Materials Interfaces demonstrates the generation of functional human iPSC-derived neurons on nanowire arrays with varying geometrical specifications. The cell/nanowire interactions range from fakir-like states to nanowire-encapsulating states depending on the array characteristics. The neurons are functional with similar kinetics of the action potentials highlighting the equivalence of the nanowire arrays for neuronal differentiation.
