MIT Engineers Build Salt-Sized Chip to Boost Phone Performance
Imagine tiny pieces, smaller than salt, that can make your phone work much better!
Engineers at MIT have made these using a special material called gallium nitride (GaN).
They built super small GaN parts and put them on regular chips.
This is cheaper and works better than before.
These new chips will keep phones from getting too hot, use less battery, and make calls and internet faster.
It's like giving your phone a super boost, all thanks to something tiny!
MIT engineers created a salt-sized chip using gallium nitride (GaN) to improve device performance.
GaN transistors are placed onto a silicon chip using a special vacuum tool, making the process cheap and scalable.
The new chip design uses copper instead of gold and operates at low temperatures.
The new chip design can improve signal strength, speed, and energy efficiency.
The technology could lead to clearer calls, faster downloads, and longer battery life in phones.
