[Laughs] ‘It had been undoubtedly an excellent threat! At time, I used to be effectively aware that it could go Incorrect and that I could become significantly less prosperous, but I just overlooked that. Curiosity has often been my strongest driving power. And luckily everything worked out.’

Sculpting nano-electrodes with a transmission electron beam for electrical and geometrical characterization of nanoparticles.

This yielded a breakthrough. In just just a few months, we were being capable to measure transport through a person one-walled carbon nanotube. Determined by low-temperature experiments by an excellent PhD student in my group, Sander Tans (now a valued colleague and professor at Delft College of Engineering having an active investigate lab at AMOLF in Amsterdam), we showed that carbon nanotubes ended up genuine quantum wires with quite long (micrometres) electronic coherence lengths — confirming theoretical predictions of metallic conduct.

Our study ranges in the biophysics of DNA to artificial cells and outside of. You should take a look under on the spectrum of our existing tasks.

Numerous associated developments followed, exactly where our group set up distinct transistor variants including solitary-electron transistors at space temperature and intramolecular nanotube junctions that acted as rectifying diodes, and coupled several transistors into little proof-of-basic principle electronic circuits.

Instance (one) of bending configurations in 3D simulations of DNA rods on nanopores. A portion of the membrane is demonstrated in grey, the rim of your pore is highlighted in crimson, and a 3D rendering on the motion in the DNA rod is exhibited.

‘Of course, I comprehend persons had been amazed at the time. At the end of the nineties, Once i cees dekker was in my forties, I had been Professor of Molecular Electronics and I have to confess that it experienced become a bit bored, I didn’t study A lot any more. The sphere went much more into the appliance facet, how you can integrate nanotubes into Digital circuits.

There was 1 difficulty however — we didn't notice any measurable electrical conduction from the single polymer molecules. We concluded that at the single-molecule level, conducting polymers were really not this sort of wonderful conductors, which was somewhat disappointing. We Consequently broadened our watch to test to search out extra promising molecules.

Instance (four) of bending configurations in 3D simulations of DNA rods on nanopores. A percentage of the membrane is proven in grey, the rim of your pore is highlighted in purple, plus a 3D rendering in the motion of your DNA rod is exhibited.

2001, discovery of one-electron transistors at home temperature based on nanotubes; realization of first logic circuits with carbon nanotube gadgets; and discovery in the molecular construction of DNA fix enzymes with AFM

Developments in nanotechnology while in the nineties manufactured setting up Digital equipment from one molecules a risk. Cees Dekker recounts how his team produced a area-temperature transistor determined by one carbon nanotube.
