Molecular Manipulation

Molecular layer patterned with a scanning probe microscope controlled by an autonomous learning agent.

About

Once we can freely arrange and combine even a handful of atoms and molecules, a myriad of designer quantum systems can be constructed and studied. We address the major challenges of SPM-based molecular manipulation in an interdisciplinary approach including experiments, simulations, machine learning and control theory.

This research is funded by an ERC Starting Grant.

Research Topics

  • Learning and control for molecular nanofabrication
  • Theory of molecular manipulation
