Graphene: Carbon in Two Dimensions

Graphene is the thinnest known material, a sheet of carbon atoms arranged in hexagonal cells a single atom thick, and yet stronger than diamond. It has potentially significant applications in nanotechnology, ‘beyond-silicon’ electronics, solid-state realization of high-energy phenomena and as a prototype membrane which could revolutionise soft matter and 2D physics. In this book, leading graphene research theorist Mikhail Katsnelson presents the basic concepts of graphene physics.

Carbon Nanotube and Graphene Device Physics

Explaining the properties and performance of practical nanotube devices and related applications, this is the first introductory textbook on the subject. All the fundamental concepts are introduced, so that readers without an advanced scientific background can follow all the major ideas and results. Additional topics covered include nanotube transistors and interconnects, and the basic physics of graphene.

Graphene brain implants.

A team of researchers from Technische Universität München (TUM) and the Jülich Research Center published results in the journal Advanced Materials that demonstrated work on a graphene-based transistor array that is capable of recording the electrical signals of the living biological cells on which it is placed. According to a statement, so-called bioelectronic applications have been proposed that would place sensors and, in some cases, actuators inside a person’s brain, eye, or ear to help compensate for neural damage.

IBM unveil latest graphene transistor research

IBM (NYSE: IBM) scientists today unveiled several exploratory research breakthroughs that could lead to major advancements in delivering dramatically smaller, faster and more powerful computer chips.

For more than 50 years, computer processors have increased in power and shrunk in size at a tremendous rate. However, today’s chip designers are hitting physical limitations with Moore’s Law, halting the pace of product innovation from scaling alone. With virtually all electronic equipment today built on complementary-symmetry metal–oxide–semiconductor (CMOS) technology, there is an urgent need for new materials and circuit architecture designs compatible with this engineering process as the technology industry nears physical scalability limits of the silicon transistor.

F1000 Dec 4th

Another week has gone by and so it’s time to reassess the investments in graphene and diamond that were made at the outset of this blog. I say outset, but in effect the blog has only been running for the past two weeks so lets cut to the chase and see how a grands worth of shares have faired in the last fortnight.

Starting with Paragon Diamonds, 3478 shares were purchased in the hope that an increase in the price of diamond would prove graphene’s elder sister is still a commodity worth investing. After two weeks of very sluggish action the price is now 26.75p per share. An investment of £1000 has been mercilessly reduced to just £930, a further £30 loss on last week and not looking good for Christmas and the New Year.

But did graphene’s champion share CVD Equipment Corporation fare any better. An initial outlay of $1000 purchased 61 shares two weeks ago, and at a selling price of $14.49 the investment continues to plummet. Now worth $884 the shares have lost over one tenth of their value.

With CVD breaking through the lower Bollinger band I would expect the market to enact some kind of rebound upwards, and with the 3 month high at somewhere in the region of $18.50 I’m hoping for a complete turnaround. Let’s face it if the share price goes any further south I’ll be swimming with penguins.
