New Bismuth Transistor Runs 40% Faster and Uses 10% Less Power
Recently in material science news from China we hear that [Hailin Peng] and his team at Peking University just made the world’s fastest transistor and it’s not made of silicon. Before we tell you about this transistor made from bismuth here’s a whirlwind tour of the history of the transistor.
The Bipolar Junction Transistor (BJT, such as NPN and PNP) was invented by Bell Labs in 1947. Later came Transistor-Transistor Logic (TTL) made with BJTs. The problem with TTL was too much power consumption.
Enter the energy-efficient Field-Effect Transistor (FET). The FET is better suited to processing information as it is voltage-controlled, unlike the BJT which is current-controlled. Advantages of FETs include high input impedance, low power consumption, fast switching speed, being well suited to Very-Large-Scale Integration (VLSI), etc.
The cornerstone of Complementary Metal-Oxide-Semiconductor (CMOS) technology which came to replace TTL was a type of FET known as the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET). The type of MOSFET most commonly used in CMOS integrated circuits is the Enhancement-mode MOSFET which is normally off and needs gate voltage to conduct.
A transistor’s technology generation is given with the “process node”, in nanometers (nm). This used to mean the size of the smallest feature that could be fabricated, but these days it’s just a marketing term (smaller is “better”). Planar CMOS MOSFETs were initially dominant (through ~28nm), then came SOI MOSFETs (28nm to 16nm), then FinFETs (16nm to 5nm), and now finally Gate-All-Around FETs (GAAFETs, 3nm and beyond).
All of that in order to say that this new transistor from [Hailin Peng] and his team is a GAAFET. It’s made from bismuth oxyselenide (Bi₂O₂Se) for the channel, and bismuth selenite oxide (Bi₂SeO₅) as the gate material. See the article for further details.
Keep in mind that at this point in time we only have a prototype from a lab and the gory details about how to mass-produce these things, assuming that’s even possible, haven’t yet been worked out. We have previously discussed the difficulty of manufacturing state-of-the-art transistors. If you’re interested in bismuth be sure to check out how to use bismuth for desoldering.

The image depicts a character with long, flowing white hair, wearing a brown coat with a black belt and a blue pendant. The character is standing in a dimly lit library, surrounded by bookshelves filled with books. Papers are floating in the air, suggesting a magical or supernatural element. The character is holding a magnifying glass and appears to be examining a book with an eye symbol on its cover. The overall atmosphere is mystical and scholarly. The image is credited to Wayne Wu and Wizards of the Coast LLC, with the years 1993-2023.

@Robo105 this is so true. Why feed the people you’ve corralled in a concentration camp? It’s a pretty sad excuse for a holocaust if you go at it half hearted.
