One and done: Single-atom transistor is end of Moore's Law; may be beginning of quantum computing
A controllable transistor engineered from a single phosphorus atom has been developed by researchers at the University of New South Wales, Purdue University and the University single-atom transistor is end of moores law Melbourne.
The atom, single-atom transistor is end of moores law, shown here in the center of an image from a computer model, sits in a channel in a silicon crystal. The atomic-sized transistor and wires might allow researchers to control gated qubits of information in future quantum computers.
Purdue University image Abstract: Abstract A Single-Atom Transistor Martin Fuechsle, Jill A. Miwa, Suddhasatta Mahapatra, Oliver Warschkow, Michelle, Y. Simmons, Centre for Quantum Computation and Communication Technology, University of New South Wales, Sydney, Australia Hoon Ryu, Sunhee Lee, Gerhard Klimeck, Network for Computational Nanotechnology, Purdue University, West Lafayette, Ind. Lloyd C. Hollenberg, Centre for Quantum Computation and Communication Technology, University of Melbourne, Parkville, Australia The ability to control matter at the atomic scale and single-atom transistor is end of moores law devices with atomic precision is central to nanotechnology.
The scanning tunneling microscope can manipulate individual atoms and molecules on surfaces, but the manipulation of silicon to make atomic-scale logic circuits has been hampered by the covalent nature of its bonds.
Resist-based strategies have allowed the formation of atomic-scale structures on silicon surfaces, but the fabrication of working devices - such as transistors with extremely short gate lengths, spin-based quantum computers and solitary dopant opteolectronic devices - requires the ability to position individual atoms in a silicon crystal with atomic precision. Here we use a combination of scanning tunnelling microscopy and hydrogen-resist lithography to demonstrate a single-atom transistor in which an individual phosphorus dopant atom has been deterministically placed within an epitaxial silicon device architecture with a spatial accuracy of one lattice site.
The transistor operates at liquid helium temperatures, and millikelvin electron transport measurements confirm the presence of discrete quantum levels in the energy spectrum of the phosphorus atom, with a charging energy that is close to the bulk value.
Previously, this has only been observed by optical spectroscopy. The smallest transistor ever built - in fact, the smallest transistor that can be built - has been created using a single phosphorous atom by an international team of researchers at the University of New South Wales, Purdue University and the University of Melbourne. The single-atom device was described Sunday Feb. Michelle Simmons, group leader and director of the ARC Centre for Quantum Computation and Communication at the University of New South Wales, says the development is less about improving current technology than building future tech, single-atom transistor is end of moores law.
As we transition to atomic-scale devices, we are now entering a new paradigm where quantum mechanics promises a similar technological disruption. It is the promise of this future technology that makes this present development so exciting.
Simulations of the atomic transistor to model its behavior were conducted at Purdue using nanoHUB technology, an online community resource site for researchers in computational nanotechnology. Gerhard Klimeck, who directed the Purdue group that ran the simulations, says this is an important development because it shows how small electronic components can be engineered. The latest Intel chip, the "Sandy Bridge," uses a manufacturing process to place 2. A single phosphorus atom, by comparison, is just 0.
The single-atom transistor does have one serious limitation: It must be kept very cold, at least as cold as liquid nitrogen, or minus degrees Fahrenheit minus Celsius. For this atom to act like a metal you have to contain the electrons to the channel. But this is a fundamental question for this technology. The structure even has markers that allow researchers to attach contacts and apply a voltage, says Martin Fuechsle, a researcher at the University of New South Wales and lead author on the journal paper.
Simmons says this control is the key step in making a single-atom device. Some scientists, however, have doubts that such a device can ever be built.
The technique we have developed is potentially scalable, using the same materials as the silicon industry, but more time is needed to realize this goal. This will lead to many more discoveries. However, on reading into the literature I could not see any practical reason why it would not be possible," Simmons says.
Now Purdue graduate students spend time studying at the University of New South Wales, and their students travel to Purdue to learn more about nanotechnology. It has been a rewarding collaboration, both for the scientific discoveries and for the personal relationships that were formed. For more information, please click here.
