A diode's color depends on the semiconductor's energy levels: red and green require narrow-bandgap materials, which are relatively easy to synthesize. In contrast, blue light has a short wavelength and high energy, demanding a wide-bandgap semiconductor — specifically gallium nitride (GaN) — which scientists did not know how to process for decades. The primary hurdle lay in growing defect-free GaN crystals and establishing a layer with p-type conductivity. For years, researchers failed to make the material conduct electricity efficiently because hydrogen atoms locked the doping magnesium in place. The breakthrough came from Japanese physicists Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, who managed to grow clean crystals, activate p-conductivity using heat, and utilize quantum wells to achieve ultra-bright emission. This invention revolutionized the world because without a blue LED, it was impossible to create white light. By coating a blue chip with a yellow phosphor or combining it with red and green (the RGB system), humanity finally developed energy-efficient LED bulbs and modern color screens for smartphones and TVs. For this monumental leap, the creators were awarded the Nobel Prize in Physics in 2014. #Science #education #facts #physicstok” memiliki 266.234 tayangan, 32.877 suka, 136 komentar, 783 kali dibagikan dalam metrik publik yang dicatat indeks ini.
