He obtained his Habilitation at the Biozentrum Basel (1996) and his PhD at the Freie Universität Berlin under the guidance of Professor W. Helfrich in 1988. His research interest is in molecular transport.
Dr. Robert Zierold
Dr. Zierold studied (Medical) Physics at the Martin-Luther-University Halle-Wittenberg. After finishing his diploma thesis at the Max-Planck-Institute for Microstructures in Halle, he performed his PhD at the Institute of Applied Physics at Universität Hamburg. Already, at the age of 33 he took a permanent senior faculty position leading the Bio-Materials Team in Prof. Blick’s group. His special research interest is in atomic layer deposition (ALD), which is utilized to prepare nano- and microstructures for application in superconductivity, thermochromics, and photonic crystals. Moreover, he and his research team are exploring tailor-made nanostructures as artificial cell culture substrates for guiding neuronal network formation and as novel detector concepts in protein mass spectrometry.
Dr. Christian Heyn
The focus of Christian Heyn’s research activities is the fabrication and characterization of epitaxial semiconductor quantum structures based on molecular beam epitaxy (MBE). MBE allows the fabrication of crystalline nanostructures from ultra-clean semiconductors with perfect control of size and composition. He studies the fundamental mechanisms of epitaxial growth including self-assembly of quantum dots (QDs) and self-rolling nanotubes. Over the last years he developed and optimized a method for the generation of strain-free GaAs QDs by a liquid metal droplets etching for applications in quantum information technology. The aim is to tailor the quantized energy levels inside the QDs and their tunability by external electric and magnetic fields. Christian Heyn has published 247 reviewed articles with 4,715 citations and an h-index of 38 (November 2022, https://www.researchgate.net/profile/Christian-Heyn)
Dr. Lars Tiemann
Dr. Lars Tiemann is scientist in the group working on Quantum Transport. After receiving his PhD in Physics working in the group of Prof. Klaus von Klitzing at the Max-Planck-Institut for Solid-State Research in Stuttgart, Germany, he was postdoctoral scholar at NTT Research Laboratories in Japan. He then continued to work on low-dimensional electron gases with Prof. Werner Wegscheider at ETH Zurich, Switzerland, before moving to Hamburg. At the Center for Hybrid Nanostructures he is also responsible for running the low-temperature group in charge of the helium liquefier.
Dr. Haisen Ta
Thomas is working as an engineer in the group. He has a long time experience in clean room work and thus is in charge of the main clean room labs of CHyN apart from our group’s laboratories.
Katja is taking care of most of the administrative work of the group.

The synergy of advanced biological cell types and functionalized micro-/nanostructured might be the key in life sciences for accelerating progress in relevant fields such as high-throughput screenings and neurodegenerative disease studies. In my work, I combined human induced pluripotent stem cell (hiPSC)-derived neurons with both nanowire arrays and 3D microscaffolds to explore their potential for targeted cargo delivery and brain-on-a-chip (BoC) applications, respectively.
Dr. Pai Zhao is leading the research of surface acoustic waves (SAW), including fundamental investigations of interaction between SAW and van der Waals materials, i.e., graphene and TMDCs, and applications of SAW strain sensors and SAW modulated liquid crystalline elastomers for displays.
Chithra H. Sharma
Dr. Sharma received her PhD in Physics in 2019 while at IISER Thiruvananthapuram working in the group of Dr. Madhu Thalakulam. She is a recipient of Alexander von Humboldt post-doctoral fellowship. She is currently working with the group of Prof. Kai Rossnagel’s group in CAU Kiel. Dr. Sharma is investigating correlated electron states in twisted transition metal dichalcogenides (TMCs) Moirè superlattices and electron-spin-resonance (ESR) and van-der-Waals (vdW) heterostructures made of TMCs. She is also interested in combining surface acoustic waves with TMC-based vdW-heterostructures.
I’m working on graphene heterostructures that I want to combine with superconducting junctions and microwave resonators. These are key ingredients for devices that could be very useful for quantum information and radioastronomy science.
Isabel González Díaz-Palacio
I work on the strategy for developing superconducting radio frequency (SRF) cavities used at particle accelerators by nanostructuring multilayers with plasma-enhanced atomic layer deposition (PEALD). The next generation of tailored thin-film based cavities would allow for more efficient and sustainable accelerators operating at higher energies. In particular, I study multilayers consisting of AlN as dielectric and NbTiN as superconductor.
My current research focuses on atomic layer deposition (ALD). Specifically, ALD is used to explore materials with insulator-to-metal transition phenomena and further construct tailor-made switchable photonic crystals. In the meantime, I am trying to extend more possibilities for the ALD technique.
My work consists of functionalization and optimization of 3D nano-printed microchannel plate detectors. Therefore, I take advantage of the design freedom offered by two-photon direct laser writing on the one hand, and the precisely controlled and uniform growth of thin films by atomic layer deposition on the other. A microchannel plate (MCP) optimized in this way could not only be an improvement for previously used MCPs, but could also expand the range of detectable particles.
