Atomic Scale Physics
We focus on the experimental study of atomically well-defined nanostructures, where the precise nature and location of every atom matters. We use low-temperature scanning probe microscopy that allows structural and electronic characterization, and manipulation of materials down to the atomic scale.
Current focus:
- Artificial designer materials using 2D van der Waals materials, molecular self-assembly, and heterostructures
- Atomic scale characterization and modification of materials based on scanning probe techniques
- Chemistry and physics of single molecules

Facilities:
The Atomic Scale Physics research group is located in Nanotalo and operates three low-temperature, ultra-high vacuum (UHV), scanning probe microscopes that are housed at the Aalto Nanomicroscopy center.
The Createc LT-STM/AFM operates at a low temperature (T = 5 K) and it is optimized for simultaneous AFM and STM experiments on the same atomic location - more details at https://www.aalto.fi/en/department-of-applied-physics/uhv-scanning-probe-microscopes.
The Unisoku USM-1300 is designed for temperatures down to 300 mK and ultra-high vacuum to perform STM and spin-polarized STM experiments in an external magnetic field of up to 11 T - more details at https://www.aalto.fi/en/department-of-applied-physics/uhv-scanning-probe-microscopes.
The Createc LT-STM/AFM operates at a low temperature (T = 5 K) and the same UHV setup houses X-ray photoelectron spectroscopy (XPS) and low-energy electron diffraction (LEED) setups - more details at https://www.aalto.fi/en/department-of-applied-physics/uhv-scanning-probe-microscopes.
