New State of Matter Could Extend Moore's Law
rennerik writes "Scientists at McGill University in Montreal say they've discovered a new state of matter that could help extend Moore's Law and allow for the fabrication of more tightly packed transistors, or a new kind of transistor altogether. The researchers call the new state of matter 'a quasi-three-dimensional electron crystal.' It was discovered using a device cooled to a temperature about 100 times colder than intergalactic space, following the application of the most powerful continuous magnetic field on Earth."
Extend it? I trust you mean CONFIRM IT YET AGAIN!
Thought so.
From comments in TFA:
The researcher, Dr. Guillaume Gervais, is director of McGill University's Ultra-Low Temperature Condensed Matter Experiment Lab. There's nothing in the journal letter about "a new state of matter". The McGill Newsroom article quotes him as saying to the interviewer, "It's actually not quite 3-D, it's an in-between state, a totally new phenomenon" as compared with the 2-D electron crystals that transistors and IC chips are made of. The interviewer, or an editor, thought "Physics -- state -- new state of matter". Engadget's Melanson picked up the error and passed it on uncritically.
TFA doesn't state any specific temperature, but I find the analogy to how "cold" space is rather troubling. Space is really "warm", as it contains energy left from the Big Bang (although no one with a common sense would describe it that way in daily talk), and saying that something is so many times colder than space really just doesn't make sense. You can always compare sizes, but as heat is a positive size, because you can't have negative energy, you can just say "this is a hundred times hotter than that" or "my freezer is two times as cold as my refrigerator compared to my living room". The one who thought of this analogy could be talking about degrees on Celsius or Fahrenheit, but then those numbers must be way below absolute zero, or 0 Kelvin, as space is just 2.7 Kelvin, or -270.7 C ( http://helios.gsfc.nasa.gov/qa_sp_ht.html ) and taking for granted he is comparing the temperature of space to 0 ÂC, that means that those crystals are actually -27070 C. And _that_ would be some real frontpage material...
You seem confused. He speaks of "a temperature about 100 times colder than intergalactic space". Intergalactic space has a temperature of about 3K. It does not make sense to talk of degrees C, since C is not an absolute scale. 100 times colder than 3K is 0.03K.
