Molybdenite outshines silicon and graphene for electronic applications

From Gizmag:

Researchers have uncovered a material that they say has distinct advantages over traditional silicon and even graphene for use in electronics. Called molybdenite (MoS2), this mineral is abundant in nature and is commonly used as an element in steel alloys or, thanks to its similarity in appearance and feel to graphite, as an additive in lubricant. But the mineral hadn’t been studied for use in electronics, which appears to have been an oversight with new research showing that molybdenite is a very effective semiconductor that could enable smaller and more energy efficient transistors, computer chips and solar cells.

Toward faster transistors: New physical phenomenon could lead to increases in computers’ clock speed

From PhysOrg.com:

In this week’s issue of the journal Science, MIT researchers and their colleagues at the University of Augsburg in Germany report the discovery of a new physical phenomenon that could yield transistors with greatly enhanced capacitance — a measure of the voltage required to move a charge. And that, in turn, could lead to the revival of clock speed as the measure of a computer’s power.

Single molecule electronics and ‘chemical soldering’

From PhysOrg.com:

Single molecule electronics is a division of nanotechnology utilizing single molecules as electronic components and its study has the ultimate goal of reducing the size of common electrical circuits. Since 1974, when Mark Ratner and Arieh Aviram from IBM first described how a single molecule was capable of working as a diode in passing current in one direction, research has moved forward in trying to develop a way to use single molecule electronics.

IBM introduces new graphene transistor

From PhysOrg.com:

In a report published in Nature, Yu-ming Lin and Phaedon Avoris, IBM researchers, have announced the development of a new graphene transistor which is smaller and faster than the one they introduced in February of 2010. This new transistor has a cut-off frequency of 155 GHz, compared to the 100 GHz previous transistor.

Transistor performance improves due to quantum confinement effects

From PhysOrg.com:

Manufacturing on the nanoscale has come a long way since Feynman’s visions of nanotechnology more than 50 years ago. Since then, studies have demonstrated how low-dimensional structures, such as nanowires and quantum dots, have unique properties that can improve the performance of a variety of devices. In the latest study in this area, researchers have fabricated transistors made with exceptionally thin silicon nanowires that exhibit high performance due to quantum confinement effects in the nanowires.

New transistors: An alternative to silicon and better than graphene

From PhysOrg.com:

Smaller and more energy-efficient electronic chips could be made using molybdenite. In an article appearing online January 30 in the journal Nature Nanotechnology, EPFL’s Laboratory of Nanoscale Electronics and Structures (LANES) publishes a study showing that this material has distinct advantages over traditional silicon or graphene for use in electronics applications.
