Given the interdisciplinary nature of our research, we combine work in our own laboratory spaces with research conducted in shared campus facilities. In our lab, we build and customize optical and electrical characterization setups, including confocal microscopy platforms tailored for 2D materials and device measurements. We also carry out exfoliation and deterministic transfer of 2D materials in-house, enabling controlled assembly of heterostructures. Device fabrication is performed in cleanroom environments, where we use Heidelberg maskless lithography and EBPG electron-beam lithography systems to define nanoscale device geometries. For structural and spectroscopic characterization, we access the university’s advanced materials facilities equipped with TEM, SEM and Raman spectroscopy suites.
In addition, we maintain dedicated space for in vitro cell culture and biological interfacing studies, allowing us to explore bioelectronic applications directly within our research program.
All our labs are located on the main campus and in the walking distance from each other to speed up the device development and measurements. Our own lab spaces are part of the biomedical building which is 3 mins away from the cleanrooms in CREOL and ECE.
We use laser-based direct write systems for photolithographic patterning of our devices on large-scale. Depending on applications we work with wafer-scale design and fabrication. We use the cleanroom in ECE, more details here.
We use state-of-the-art EBL system to patten nanoscale structures and devices. The Raith EBPG 5200 Plus allows for patterning of the structures with feature sizes of 5nm. We access this instrument in the cleanroom at CREOL, see here.
We perform 2D material transfer in our own chemical fume hoods designed for safe work and preserving clean environment required for the high quality material work.
We design and build custom measurement setups for recording electrical signals from our devices. Depending on the device geometry, we perform two- or three-probe measurements. Data acquisition and experiment control are automated using LabView and Python, allowing for high-throughput measurements.
We integrate optical excitation and spectroscopic detection through a confocal microscope pathway, while maintaining electrical probe access to individual devices. This configuration allows us to measure photocurrent and light emission from a single device at a time with high spatial precision.
We analyze our material quality, device and EBL-patterned nanostructures using scanning electron microscopy (SEM) available through shared facilities, allowing us to visualize nanoscale details and verify material quality after transfer and results of fabrication steps. We use Advanced Materials Processing and Analysis Center.
We design and build high-sensitivity confocal microscopy systems tailored for recording optical and bioelectrical signals. By optimizing optical pathways, detector selection, and vibration isolation, we achieve the sensitivity required to measure weak signals from nanoscale devices and living systems.
We integrate biological systems with our nanoscale devices by seeding cells directly onto device surfaces. Cell culture is performed entirely in-house, using our cell culture hood and CO₂ incubators, which provide a controlled and sterile environment for maintaining healthy cell populations.
In our lab, science is both safe and fun. We prioritize safe laboratory practices and a collaborative, respectful environment. We also believe that great science happens when people feel encouraged, connected and happy. So we always make room for curiosity, creativity, and fun. More here.
