Three atoms thick. According to a paper published this week in the science journal Nature by a group of researchers from Cornell University, that is the breadth of the transistors that can now be produced using an experimental — and highly conductive — material called transition metal dichalcogenide (also called a TMD). We aren't talking five atoms thick, or even four (because any schmoe with a hobbyist chemistry set can do that), but transistors rendered at a thickness of just three atoms. As it applies to theoretical science and human achievement, the harnessing of TMD for practical use is quite...

Graphene is a sort of super material for electronics; it’s thin, durable, light, transparent, and flexible, and Samsung says that it’s developed a way to synthesize the substance so it can speed of the commercial development of graphene and thereby usher in a new era of electronics development. Samsung noted that graphene has “one hundred times greater electron mobility than silicon” and is ideal for flexible displays and wearable computing devices. Maybe someday soon? The breakthrough came from the company’s Samsung Advanced Institute of Technology (SAIT) partnership...

Made in IBM Labs: IBM Scientists Demonstrate World's Fastest Graphene Transistor Holds Promise for Improving Performance of Transistors YORKTOWN HEIGHTS, N.Y. - 05 Feb 2010: In a just-published paper in the magazine Science, IBM (NYSE: IBM) researchers demonstrated a radio-frequency graphene transistor with the highest cut-off frequency achieved so far for any graphene device - 100 billion cycles/second (100 GigaHertz). This accomplishment is a key milestone for the Carbon Electronics for RF Applications (CERA) program funded by DARPA, in an effort to develop next-generation communication devices....

It has been predicted that existing manufacturing materials used in microchips will eventually hit a wall that no amount of R & D can overcome. As a result researchers are looking into several other technologies such as Graphene."When current silicon transistor technology goes below 10 nanometers in size, it's predicted it will run into the laws of physics and will no longer be able to create reliable transistors.??Graphene, on the other hand, is already seeing working transistors in the sub-10 nanometer range. The researchers say their latest, unpublished work has used graphene to make transistors...

Companies have been trying to find a way around Moore's Law for quite some time now, and a large part of that search involves new materials. One such material is called Graphene, and can be made into flexible sheets only a single atom thin."Graphene is mechanical tough, flexible, transparent, and a great conductor of heat. The new research shows that it would make an ideal double both in transistors and in interconnects, replacing silicon and copper to form ultra-high frequency circuits. Further, it could be ideally applied to vast amount of applications including photovoltaics,...
