Okay, I studied ASIC design in college. It was actually my specialization, though I'll admit I was never able to land a job in ASIC design. But still, I took those classes through the 500 level, most of the way to a masters and created functioning silicon. I know every word mentioned in there. I'm familiar with every concept mentioned. And yet, it all sounds like gibberish. n-type and p-type are determined by their substrate. n-type, negative charge. p-type, positive charge. The difference between n-type and p-type is if you apply a positive charge to the gate to turn it on, or apply a negative charge to the gate to turn it on. But historically, p-types are extremely large on silicon, and as such, takes up a lot of real estate, so because of that though CMOS is ideal for leakage speed, nobody uses them, because they're too expensive to produce. Everybody strictly uses n-type transistors. How are you changing the transistor type without fundamentally changing the charge of the substrate. I mean, hell, it'd be a big enough of an advancement just to make a p-type that's the same size as an n-type, and to hell with them switching.

I'm not 100% sure on this, but the basics are that if this works, any electronic device that relies on transistors could be manufactured cheaper and smaller becuase of not needing to include current switching technology. In other words, future devices like various PC components can be made even smaller and more efficient. How much? That I do not know.

The article tells you what you need to know: "could lead to smaller semiconductors that require far fewer transistors than today's devices"

Be a proactive reader, not passive, no matter how bland the material is.....

Did anyone else read the title of the article as, "Universal Translator Could Enable Much Smaller Circuits."

I was a bit confused, but it makes sense now. lol

I'm not sure why, but I laughed. Thank you sir.

I'm not sure where you studied, but this is false. In modern digital IC's, CMOS is absolutely used. The industry abandoned pure NMOS and pseduo-NMOS back in the early 80's due to power concerns and switching characteristics. In general, yes, you get better drive strength, etc. with NMOS vs. PMOS due to the differences in electron vs. hole mobility, thus leading to the sizing disparity you cited. But that difference is a fact that digital IC designer have lived with for 30+ years. To say that no one uses p-type transistors is crazy.

You need to read the article closer. The novel advance is not relying on dopant concentrations to determine p-type vs. n-type. Instead, they are relying on a mechansim to modulate the charge carrier injection directly at the Schottky junction. In other words, they have a structure which allows the device to change whether electrons or holes are the majority carriers directly at the junction, thus determing whether it is configured as n-type or p-type.

"Future work will focus on improving the transistor's performance."

Why don't they work on massproducing what they have, if it's already superior to existing technology? I keep hearing about supposedly revolutionary things being developed, but nothing ever gets released. If it is too expensive to manufacture such radically different technology, then they should research improved manufacturing processes.

you studied current technology which is silicone based where band gap is created by doping of adjoint areas. current research is exploring other technologies such as use of nanowire, with goal to eventually move from silicon to carbon.

you may have proper education but you either don't know how to read or your claims are inaccurate and you have no idea what "intrinsic" semiconductor is. read closer - this transistor is still made from silicon but uses nanowire and there is NO DOPING, they use INTRINSIC silicone. no distinct areas of different material are persent. this 'p' and 'n' is NOT p and n, it only ACHIEVES CHARACTERISTICS of p or n...

a few questions come to mind, will it be cost effective? will they be able to make it perform as well as current transistors. heat, speed, efficiency?

Kindly note the article title specified "could enable" which has a different meaning from "enables". There was no speculation whether this can actually be used for a circuit or that it is commercially viable. If folks are wild to fund something promising, just let me know. I have some really nice pixie dust and for the right funding I will promise you anything. As a heads up, pixie dust works best with government money. The use of other people's money fosters a broader vision.
