through the straight wire. Now, Berggren is rekindling


Buck’s ideas about supercon- ducting computer switches. “The devices we’re making are very much like cryotrons in that they don’t require Josephson junc- tions,” he says. He dubbed his superconducting nanowire de- vice the “Nano-Cryotron” in trib- ute to Buck. The nano-cryotron uses heat


to trigger a switch, rather than a magnetic field. In Berggren’s de- vice, current runs through a su- perconducting, supercooled wire channel, intersected by a smaller wire, the choke. When current is sent through the choke, its super- conductivity breaks down and it heats up. Once that heat spreads from the choke to the main chan-


nel, that channel also loses its su- perconducting state. Berggren’s group has already


demonstrated proof-of-concept for the nano-cryotron’s use as an elec- tronic component. A former stu- dent of Berggren’s, Adam Mc- Caughan, developed a device that uses nano-cryotrons to add binary digits. Berggren has also success- fully used nano-cryotrons as an in- terface between superconducting devices and classical, transistor- based electronics. Berggren says his group’s su-


perconducting nanowire could one day complement, or perhaps com- pete with, Josephson junction- based superconducting devices. He thinks the nano-cryotron may one day even find a home in supercon- ducting quantum computers. Web: www.news.mit.edu r

Assemble Batteries with High Power & High Storage Capacities


Advanced solutions for Electric Vehicles, Charging Stations, & Energy Storage Systems


Sonobond’s ultrasonic metal welders quickly and reliably weld up to 100 layers of anode and cathode foils – as thin as seven microns – to battery tabs and terminals, without tearing! They also easily weld the large wire bundles and HV terminals required for high power and high storage capacity batteries.


Using our patented Wedge-Reed System – with no external heat, current or fi llers – our


units create strong, solid-state, highly conductive welds, elimi- nating metallurgical defects such as porosity and intermetallics that commonly exist in fusion welds.


This System welds tinned and oxidized metals – a unique ability unmatched by any other ultrasonic system – as well as stranded copper wire bundles up to 100 sq.mm cross section.

the ophthalmologist, OCT uses infrared light to illuminate the retina. The radiation is selected in such a way that the tissue to be examined does not absorb it too strongly and it can be reflect- ed by the inner structures. The new method uses ex-


tremely short-wave UV light for its OCT. “This is due to the size of the structures we want to im- age,” says Wiesner. In order to look into semiconductor materi- als with structure sizes of only a few nanometers, light with a wavelength of only a few nano - meters is needed.

band XUV (extremely short- wave UV light) in an ordinary
