Computerworld website published the article and claimed, IBM researchers obtained the great technological break-through in the field of electronics of spinning a few days ago, can lengthen the cycle of spinning of electron 30 times, thus expected to break through ” terminal predicament ” that memory trade faces ,Initiate the new round ofly in the future ” Store the revolution ” . The following is an article full text:
The famous science periodical ” Nature ” will publish a thesis written by IBM researchers this week, they claim to obtain a great technological break-through in the field of electronics of spinning, can be in order to improve the memory and store the memory ability of the apparatus, can reduce its energy consumption greatly at the same time notably.
What is electronics of spinning?
Electronics is to spin ” Spin and move electronics ” Abbreviation,it is that it can last electron at magnetic field for spin and be combined to last head, record and read the digit data on the semi-conductive material.
Through changing the relative axial of the electron in their spaces ‘ Upwards or downward ,The physicist can represent the location of data with it. For example, the electron is ” 1 ” on the upward axle ,And the electron is on the downward axle ” 0″ .
For a long time, it face one of inherent problems, because electron electronics of spinning ” upwards or downward ” Direction state can only keep 100 psec – -1 equivalent to 1/1,000 billion for one second ‘ 1 is received for 1‰ of second . 100 psecs are not enough to carry on operation, so the transistor can’t finish the operation function, it is not lasting that the data are stored.
IBM lets to spin the electron is danced big ” The group dancing ”
In publish in the research of ” the Nature “, the intersection of IBM and research institute and federal Institute of Technology are abbreviate as ” ETH “, Zurich of Switzerland, Solid physical laboratory announce, a synchronous method that they find can spin electron cycle lengthen, receive second to 1.1 by 30, this is the operation cycle of 1 GHz processor too.
Scientist Saris in Ji’an Gian Salis of the union author of this thesis, physical research group of nanometer of IBM research institute Show, the scientist of IBM utilizes ultra short laser pulse to monitor the spin that hundreds and thousands of electrons produce at the same time in the small places of one, thus understand the change of the state of spinning of these electrons.
Generally, these spin the electron will be rotated at random and lost directionality rapidly. In the research, the researchers of IBM and ETH have found how to present neatly the method that a banding arranges of the free electron for the first time, this kind of permutation is known as again ” The invariable spiral of spinning ” persistent spin helix, is abbreviated as PSH .
Saris points out, ” spins and locks ” This concept was put forward first to 2003, some experiments found that this kind focused on sign that existed to prove this kind, but no one has observed this course directly up until now.
” the rotation of the direction is totally independent to spin ” Saris says, ” we can let this kind realize moving ahead simultaneously rotatably now, thus all rotate along the same direction while letting the electron keep spinning, just like uniform group dancing. ”
“We have already totally grasped this course, and already proved this theory. ” He adds.
It is electronic it is spiral to spin pursue mode and ” The invariable spiral of spinning ” PSH picture comes from computerworld
Create the electronic industry’s new opportunity
The researchers of IBM adopt GaAs as its main semi-conductive material, this is current electronics industry, diode and a kind of commonly used materials of solar cell.
The computing technology of today carries on code and treatment of the data by electric charge change of the electron. But researchers point out, when the size of the semi-conductive material lessens to the electron and can not flow controlledly, this technology has been limited.
For example, the circuit width that NAND flashing memory products used has already been smaller than 20 nanometers, this is close to the atom size size. But through controlling the spin but not electric charge of the electron, electronics of spinning can overcome this predicament that memory trade faces.
This kind of electronics is understood newly, not only can let the scientist control the electromagnetic sports within the apparatus unprecedentedly to spinning, also made the electronic apparatus with higher efficiencying creates the new opportunity.
In the field of electronics of spinning, IBM is not the only person who studies intensively technology.
Three years ago, material physics of Strasbourg of France and physicists of the chemical research center set up new laser technology on the basis of electronics of spinning, and obtained Nobel Prize for physics in 2007.
These French physicists have found a method, the memory that can make use of laser to accelerate the hard disk is imported / exported, make it than existing to read and write the speed to raise by 100,000 times.
One of the questions that electronics meets of spinning, a magnetic sensor used for measuring the location of data is too slow in speed. But in 2007, a research of France is published in the scientific periodical ” nature – physics ” Nature Physics Go, research group this use ” fly to second ” namely 1‰ of 1.1/1,000,000 billion psecs of one second The laser produces the laser pulse ultra and quick in speed, thus change the electron and spin, so has accelerated reading and writing the course.
The researchers of IBM say, say the break-through which they made has opened up the road for transistor and non-volatile memory, the energy consumption of such new memory technology will be well below NAND flashing memory technology of today.
Need extreme low-temperature environment
However, a very great crux lies in – -Researchers can’t receive the ideal result at the room temperature yet at present, but the temperature of the normal range is produced to the reality of processor and memory apparatus very important. Come, look at present, experiment this in low to 40 Kelvin only Extreme at low temperature could go on.
“There is no such an apparatus now, but this is that one is broken through, we grasp and lengthen the method of cycle of spinning in the ditch one of electron. ” Saris say ” and then we want one thing that do, it spin for cycle Lengthen 30 times. ”
