Could modern, nanoscale vacuum tubes replace transistors?
Public Group active 2 years, 11 months agoOne of the several topics we’ve covered many 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 still search for long-term in order to this problem, no known next-generation technology is expected to restart silicon scaling as well as for coming back to traditional clock speed gains.
Researchers at the California Institute of Technology think they may have a solution to this problem — one that involves returning to a early technology to unravel the problems of existing methods. Vacuum tubes, primarily based Dr. Axel Scherer, may be key to improving transistor performance and lowering power consumption.
Chances are, when you believe vacuum tubes, you involving old radios or possibly Aopen’s AX4B-533 “TubeAmp” mother board. The systems that Dr. Scherer and his research team are working on are nothing beats classic vacuum tubes — according towards team, the structures are roughly 1,000x smaller in comparison human blood cell, that make them 6–8nm. Trouble people with modern CPUs is that they suffer from significant numbers of electricity leakage — Scherer’s designs would use leakage current to turnover states on purpose, thereby improving efficiency and functionality.
One explanation for this studies are that Scherer thinks the microprocessor teams scaling below 10nm will encounter factors. The properties of silicon apparently change during that point, becoming both elastic and emitting light. “It’s a different material, and it gives you this different behavior,” Scherer told the new York Times.
Can tubes replace transistors?
Dr. Scherer isn’t trying to reinvent the transistor or replace the silicon economy. Boeing is funding his research due to its potential applications in space and aviation technologies, and silicon will obviously be the 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 lot of problems become solved between here presently there. First, there’s the question of manufacturing — can we crank out tens of thousands of vacuum-based processors in per month? 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, and how will they integrate into existing products?
These might sound like boring questions compared to a technology’s fundamental promise, but the boring questions are what ultimately determine if or not tech for you to market. When we talk about Intel within build faster CPUs, it doesn’t mean silicon may be the fastest semiconductor ever. It indicates that Intel can’t locate 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, nevertheless the cost and manufacturing challenges are an enormous roadblock to any different technology establishing itself as a silicon player. Neither carbon nanotubes nor graphene have done so, despite huge initial hype. There’s something satisfying in the idea that a century-old technology end up being adapted and improved with enough force that it boosts modern computing, but it’s to be able to take so much of expensive work to prove it would possibly do as.
