American researchers said they use carbon nanotubes to replace silicon as raw materials, allowing memory and processors to stack together with three-dimensional way, reducing data between the data, thus improving the processing speed of computer chips, using this The operation speed of the 3D chip developed by the method may reach 1000 times the current chip. One of the researchers, Dr. Max Schamar, a Ph.D., a Ph.D., Max Schamar, an electronic engineering, hindering the computer's operational speed, the data is in that the data is turned back and forth between the processor and the memory consumption a large amount of time and energy.
Carbon nanotubes allow memory and processors to be stacked together with a three-dimensional manner, thereby significantly increases the running speed of the chip.
However, solving this problem is very difficult. Memory and central processors (CPUs) cannot be placed on the same wafer because the silicon-based wafer must be heated to about 1000 degrees Celsius; and many metal originals in the hardware are melted at a high temperature.
To this end, Schilakol and Tutor Sabhas Mitra, etc., turned its attention to carbon nanotubes. Schrakel said that carbon nanotubes have a lightweight, and the hexagonal structure is perfect. It can be treated at low temperatures, compared to conventional transistors, more conductive, and can support fast switches, so Its performance and energy consumption are far better than traditional silicon materials.
But using carbon nanotube manufacturing chips is not easy. First, the growth mode of carbon nanotubes is very bad; secondly, a small amount of metal carbon nanotubes present will damage the performance of the entire chip. Researchers want to solve these problems, and manufactured the world's first carbon nanotube computer in 2013. However, this computer is slow and cumbers, and only a few transistors.
Now, the researchers have been more step, developing a method that allows memory and transistor layer stacked, and the new 3D design method has significantly reduced the "commuting" time and new structure of the data between transistors and memory. It is 1000 times the existing chip. Moreover, the research team also develops a new chip architecture, developing multiple sensor wafers, which can be used to detect infrared, specific chemicals, and the like. Next, they intend to upgrade this system to create a larger and more complex chip.

The evolution of electronic components has never stopped, they become smaller and smaller, more and more powerful, and more cheap, at the same time, scientists have never stopped the pursuit of speed. Two years ago, a scientific research team of Stanford University developed the first computer in the world based on carbon nanotube manufacturing, and took the first step in challenge the "silicon chip" computer manufacturing mainstream material; two years later, Scientists let this chip become fashionable 3D carbon nanotube computer chips, we can't help but sigh the scientist's imagination, even new stacking methods can increase the speed of the computer chip to 1000 times, must be a good job!
