Could modern, nanoscale vacuum tubes replace transistors?
Public Group active 2 years, 11 months agoOne of the topics we’ve covered multiple times at ExtremeTech is the issue of continuing to scale semiconductor technology, and the attached problem of improving chip performance without increasing clock speed. While Intel additional manufacturers continue to search for long-term solutions to this problem, no known next-generation technology is expected to restart silicon scaling and for a return to traditional clock speed gains.
Researchers at the California Institute of Technology think might be have a solution to this problem — 1 involves returning to a early technology to solve the problems of existing methods. Vacuum tubes, as stated by Dr. Axel Scherer, could key to improving transistor performance and lowering power consumption.
Chances are, when you think vacuum tubes, you involving old radios or possibly Aopen’s AX4B-533 “TubeAmp” system board. The systems that Dr. Scherer and his research team are doing are nothing beats classic vacuum tubes — according on the team, the structures are roughly 1,000x smaller in comparison human blood cell, which could make them 6–8nm. Trouble people with modern CPUs is that they suffer from significant amounts of electricity leakage — Scherer’s designs would use leakage current to turnover states on purpose, thereby improving efficiency and overall performance.
One reason for this principals are that Scherer thinks the microprocessor teams scaling below 10nm will encounter problems. The properties of silicon apparently change at that point, becoming both elastic and emitting light. “It’s a different material, and it gives you this different behavior,” Scherer told the actual York Times when.
Can tubes replace transistors?
Dr. Scherer isn’t getting as much exercise reinvent the transistor or replace the silicon financial crisis. Boeing is funding his research due to the potential applications in space and aviation technologies, and silicon will obviously function as gold standard for everyone for quite a while. It’s still interesting to consider the question: Could such a fundamentally different technology, shrunk to a microscopic scale, solve issues of transistor scaling and performance?
Maybe — but there’s a involving problems to be solved between here and there. First, there’s the question of manufacturing — will any of us crank out tens of thousands of vacuum-based processors in thirty day period? What does it cost to build these solutions, switch out manufacturing hardware, and build an ecosystem around these kinds of? Can they built quickly enough to maintain current production rates, therefore how will they integrate into existing product lines?
These may look like boring questions rather than a technology’s fundamental promise, but the boring questions are what ultimately determine if or not tech for you to market. Many of us talk about Intel will certainly build faster CPUs, it doesn’t mean silicon could be the fastest semiconductor ever. It indicates that Intel can’t find a method of building faster chips that’s cost-effective, scaleable, and likely to last multiple product generations.
Miniature vacuum tubes could evolve into a major driver of PC performance, especially when they can be manufactured at scale, but the cost and manufacturing challenges are an enormous roadblock to any different technology establishing itself as a silicon competitor. Neither carbon nanotubes nor graphene have done so, despite huge initial hype. There’s something satisfying in the concept that a century-old technology could possibly be adapted and improved relevant that it boosts modern computing, but it’s going to take so much of expensive work to prove it can do so.
