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 related problem of improving chip performance without increasing clock speed. While Intel and also other manufacturers still search for long-term solutions to this problem, no known next-generation technology is expected to restart silicon scaling and allow for coming back to traditional clock speed gains.
Researchers in the California Institute of Technology think they may have a strategy to this problem — the one that involves in to a very old technology resolve the problems of existing methods. Vacuum tubes, according to Dr. Axel Scherer, may be key to improving transistor performance and lowering power consumption.
Chances are, when you believe vacuum tubes, you think about old radios or possibly Aopen’s AX4B-533 “TubeAmp” system board. The systems that Dr. Scherer and his research team are perfecting are nothing like 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 simply because they suffer from significant numbers of electricity leakage — Scherer’s designs would use leakage current to flip states on purpose, thereby improving efficiency and overall performance.
One reason for this studies are that Scherer thinks the microprocessor teams scaling below 10nm will encounter complaints. The properties of silicon apparently change at that point, becoming both elastic and emitting light. “It’s a different material, therefore it gives you this different behavior,” Scherer told brand new York Moments.
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 its potential applications in space and aviation technologies, and silicon will obviously function as 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 to be solved between here presently there. First, there’s the question of manufacturing — will any of us 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 them? Can they built quickly enough to maintain current production rates, and in what way will they integrate into existing brands?
These may look like boring questions over a technology’s fundamental promise, nevertheless the boring questions are what ultimately determine if or not tech for you to market. When we talk about Intel not being able to build faster CPUs, it doesn’t mean silicon could be the fastest semiconductor ever. It indicates that Intel can’t choose a method of building faster chips that’s cost-effective, scaleable, and likely to last multiple product versions.
Miniature vacuum tubes could evolve onto a major driver of PC performance, especially when they can be manufactured at scale, nevertheless the cost and manufacturing challenges are a tremendous 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 be adapted and improved to the point that it boosts modern computing, but it’s gonna be take an awful lot of expensive work to prove it does do as.
