Putting 100 trillion Field Effect Transistors (FETs) on a one square centimeter chip may become possible using graphene walls. The term “graphene walls” in this context describes tiny strips or “nano-ribbons” of carbon atoms. Other researchers have developed ideas for creating cheap and flexible lighting and display substrates made of graphene components embedded in plastic. [...]

A voltaic pile is a group of galvanic cells that are joined together as a circuit in series, forming an electric battery. While it is possible that primitive batteries were in use for several thousand years prior, Alessandro Volta, assembled the first well documented working battery. Volta was following up on Luigi Galvani’s famous experiment [...]

Fundamental electronics is being changed by the “memristor”, a device that basically acts like a variable resistor and is capable of remembering the state it was in. This is significant because a single memristor may be able to replace many transistors and capacitors, making possible much smaller electronic circuits, and because it seems that it [...]

Transposing graphene into graphane by adding hydrogen seems to offer great possibility in the development of products based on both substances. Other forms of chemical modification my continue to develop even more possibilities in the future. Scientists discover ground-breaking material: Graphane – [physorg.com] Graphene, which was discovered at the University in 2004, is a one-atom-thick [...]

In 1965, Gordon Moore (co-founder of Intel) wrote an article about the rate at which the number of transistors inside an integrated chip was increasing. By 1975, he had focused the statement on a rate of doubling the number of transistors every two years. This has become known as “Moore’s Law”. Such an exponential rate [...]

Heinrich Geissler and Julius Plucker use Geisslers new vacuum pump to evacuate the atomosphere inside a glass tube. Plucker, a young professor at the University of Bonn, discovered that a glowing stream could be produced when electricity was passed through electrodes embedded in the glass tubes and that the stream responded to a magnet. Plucker [...]

In 1854, Heinrich Geissler invents the mercury vacuum pump, which leads to high quality vacuum tubes, which in turn leads the invention of the transistor.

In 1947, John Bardeen, Walter Brattain and William Shockley led a team at Bell Labs that produced a semiconducter amplifier device that is now known as the transistor. While patents were filed in 1925 by Julius Lilienfeld and in 1934 by Oscar Heil for “field effect transistors”, historical credit for the transistor has gone to [...]
