Getting molecules to behave exactly the way we want has been the holy grail of molecular electronics for decades. Despite significant research and investment, we’re still chasing that dream.

Our approach? Go back to the fundamentals and ask the tough questions:

🔹 Can we establish design rulesfor molecular electronics?
🔹 Can we achieve a one-to-one correlation between molecular structure

        and electron transport properties?
🔹 What’s the molecular mechanism at play, and how can we tweak it?
🔹 Can external stimuli enhance or fine-tune functionality?

This research thread dives deep into:

⚡️ Molecular design
⚡️ Device fabrication
⚡️ Electron transport & cryogenic measurements
⚡️ Nano transport & in-operando spectroscopy

We are looking for electricaland electronics engineers, physicists, mathematicians, and biologists whoare ready to challenge the status quo. Let’s build the future. 🚀
