This weekend seems to be a time when research advancements are being published one after another.
First there was the quantum physics-based nano loudspeaker plan and, now, IBM is revealed to have made the smallest ever carbon nanotube transistor.
About one nanometer smaller than the assumed limit of silicon transis... |

This is not the first time the world hears about cotton transistors, but it is the latest update on the project that a multinational team of scientists are working on. Some might remember that, back in October, we mentioned how some scientists had managed to use cotton in the making of transistors. A multina... |

Graphene is showing off its wonder material properties yet again, this time actually demonstrating, or being demonstrated to, have what it takes to liquefy.
Granted, liquefy might not be the correct word, since graphene is more of a molecular compound than anything else, so terms like solid, liquid and gaseous do... |

While today's technology is made up of a variety of device and component classes, each aimed at a specific set of tasks, what they have in common is their use of silicon-based field-effect transistors (FETs). So far, silicon has been central to computing because of its very high carrier mobility, However, IBM Re... |

Moore's law accurately predicted computing power evolution for the last four decades, but in several years or so, maybe less than two decades, it will no longer be able to do so, unless the silicon material used to fabricate computer chips is soon replaced. Moore's law basically states that the number of tr... |

Stop looking for the most powerful computer in the world, you've already found it long ago, but are just not aware of it. We might not have the greatest memory to help us, however when it comes to processing power, our own brain is the ultimate computational machine. No wonder that computer processor designers a... |

The term solid-state device is mostly associated with electronic components. Almost all the electronic equipments we use today are composed of solid-state electronic devices. The word 'solid' refers to the fact that inside the electronic component there is no mechanical action taking place. The expression o... |

In 1965, Gordon E. Moore, co-founder of Intel, predicted that the processing power of computers will double every two years, meaning that the number of transistors placed inexpensively of a microchip will increase exponentially. Moore's law, as it is currently known, describes pretty accurately the computing adv... |

The transistor has just celebrated its sixtieth anniversary and it's been about 50 years since it was first integrated into a silicon chip. These tiny switches make a true "neuronal link" inside a processor, but judging by the rapid evolution in the chip world they tend to become useless soon.The need for more a... |

Co-founder of the Intel Corporation, Gordon E. Moore, predicted in 1965 in a paper that the number of transistors that can be inexpensively placed on an integrated circuit would grow exponentially and duble every two years. Since then this prediction has become known as Moore's Law and described relatively accur... |

Imagine how our lives would be had Fujio Masuoka not invented the flash memory back in the eighties. We would have never known the miracle of thumb drives or even subscriber-identity-modules in mobile telephony, not to mention memory cards or portable MP3 players. They would have never been born. Or, maybe someone wo... |
