New Delhi, June 19 -- What if your next phone call was clearer, your downloads faster, and your battery lasted longer - all thanks to a material smaller than a grain of salt? MIT engineers have just unveiled a breakthrough that could make this a reality, using gallium nitride (GaN) to supercharge the chips inside our devices.

For years, GaN has been the gold standard for speed and power in electronics, outshining traditional silicon - especially in high-speed communication and demanding devices. The catch? GaN has always been too expensive and tricky to use in everyday gadgets. But MIT's new fabrication method changes the game.

Instead of building whole chips from GaN, the MIT team created thousands of tiny GaN transistors on a single w...
