Single Molecule Transistor A Reality

Petersko writes "A team from the University of Alberta has proven for the first time that a single molecule can switch electrical currents off and on, a puzzle that scientists worldwide have been trying to crack for decades. The finding could revolutionize the field of electronics, providing a leap ahead for everything from computers to batteries to medical equipment."

      Well, there is a difference between those statements in my opinion. From a philosophical viewpoint, (or a metaphysical one to be more specific) the Mind does not deal in Failure - any and all actions taken succeed. If it is failure you undertake - it is failure you will succeed at.

      This is the statement that Yoda is making, you either do something, or you choose to fail at something.... either way, its a chosen coarse of action at which you will succeed. It fits well into the Jedi philosophy as it is more than just closely modelled on Zen + Shinto concepts.

      interesting discussion. our paper actually goes well beyond the HP work mentioned above. in fact, if you read further on the HP work, you will see that they eventually discovered, as many suspoected, that they had no (active) molecules in their device. the rotoxane, while a brilliant achievement of chemical synthesis, played no role in the observed current voltage spectra. so detailed characterization is very important. in the work we published today, for the first time it is possible to say definitively that one molecule is characterised - not more or less than one. we know where every atom is and we know the congifuration of the molecule. the other key to this work is that we have managed to make two electrodes serve as three. that is a crucial step as there isn't room to have three fine probes converge on a volume the size of a molecule lke styrene. the key is in the ability to charge one single silicon surface atom, with one single electron, near the one single molecule. the result is like a conventional field effect transistor. it is a robust effect that works at room T - unlike say the break junction work at cornell. i hope that helps answer some of the questions.

Even so, if these computers would be 1 million times faster than today's computers, and assuming they cannot be made faster or smaller (because they are already down to single molecules), then each CPU should be designed to last forever - NOT to degrade.

According to that Nature article, previous groups relied on metalmoleculemetal types of molecular junctions. Apparently, these junctions have extra geometric complexity due to the metal-molecule coordination that can complicate the charge transport measurements. This group avoided the "geometric uncertainty" by using a junction on a semiconductor (silicon) instead of a metal. They apparently added a carbon atom with an unpaired electron as a 'dangling bond' on the surface of the silicon electrode to form the molecule-electrode interface. The interface is then a covalent bond, instead of the more complicated coordination bond from other molecular junctions.

    Nanotube-based transistors came before these, too, though that's a bit of a cheat since nanotubes can be microns long.

  114. lots of room for Moore's Law by peter303 · · Score: 1

    Since even the smallest silicon switch still contains at least a billion atoms/molecues, then you have at least 30 doublings of Moore's law to continue :-)
    Probably quantum noise would sink long before then.

  116. Who needs transistors anyway? by rice_burners_suck · · Score: 1

    I don't understand why we need these newfangled transistor thingies anyway. Why, when I was your age, logic was handled using relays. Why, it took only eleven minutes for our computer, here at Building B, to add two numbers, and that includes the time it took to enter the numbers. All these newfangled transistor contraptions don't do a darn thing, I tell ya. Yes sir, I swear it, they're unnecessary.

    This is hardly desktop science. They had a roomful of equipment that seemed to need a hellish amount of cooling.

      No, no cooling, it was all done at room temperature

    So that means we're getting ever closer to those gel-pack computers like in most sci-fi shows? That'd be really cool to start seeing those. Maybe the imac of 2050 or 2100 will be called the iGel, and will come in seven different colors? :)

    While this is an amazing feat, I would like to refute the 'first molecular transistor claim'

    Carbon nanotubes are molecules, and are well known to work as transistors, even at room temperature. For instance, see these papers:

    Room-temperature transistor based on a single carbon nanotube
    S. J. Tans, A. R. M. Verschueren, and C. Dekker
    Nature 393, pages 49-52 (1998)

    Carbon nanotubes single-electron transistors at room temperature.

    Disclaimer: I wrote that last paper, there are many more papers about nanotube transistors, but these are some of the most cited ones.

    There are even single-atom transistors around, see

    Coulomb blockade and the Kondo effect in single-atom transistors,

      Interesting that if you RTFA, nowhere do they mention "molecular transistor"; its only through the insatiable hype machine that these false claims are made.

      The moral is that science & PR don't mix: one is based on truth, the other on lies.
