Intel explores beyond silicon transistors

Intel researchers layered the compound semiconductors, called indium gallium arsenide and indium aluminum arsenide. When these materials are stacked, their electronic properties interact to form quantum wells–places where charged particles such as electrons can be confined–that act as transistors, says Michael Mayberry, director of components research and vice president of Intel’s technology and manufacturing group. …

Nanolasers to help heat assisted magnetic recording to achieve 10 terabit per square inch density

Researchers at the University of California, Riverside (UCR), and at the University of Houston, in Texas, who have developed the nanolaser, say that it could lead to hard disks with 10 terabits of data packed into a square inch. 50 times more than current hard disks can carry up to 200 gigabits per square inch. …

New fast and cheap nanosoldering technique

Nanowerk reports on the work of Alex Zettl “Our radically different approach of directly contacting nanostructures via nanosoldering is simple and relies on cheap, well-established technologies: optical microscopy and micromanipulation. We realized that we could produce sub 100 nm solder spikes, used to contact nanostructures, by a simple technique. Much as a glass-blower can pull …

Nanorobots for drug delivery

Adriano Cavalcanti is CEO and chairman of CAN Center for Automation in Nanobiotech. Adriano and his coleagues have proposed a nanorobot platform should enable patient pervasive monitoring, and details are given in prognosis with nanorobots application for intracranial treatments. This integrated system also points towards precise diagnosis and smart drug delivery for cancer therapy. nanorobot …

Nanotube-producing bacteria show manufacturing promise

The research team believes this is the first time nanotubes have been shown to be produced by biological rather than chemical means. It opens the door to the possibility of cheaper and more environmentally friendly manufacture of electronic materials Genus Shewanella. The nanotube filaments produced by biological means could point toward semiconductor manufacturing processes with …
