Taming the Rebels: Technology Surface Passivation for Reduced Recombination In the world of semiconductor devices, efficiency is king. We strive to squeeze every ounce of performance from each tiny transistor, every solar cell, every LED. But there's a silent saboteur lurking within these intricate structures: recombination. Think of recombination like a leaky faucet in your energy system. Electrons and holes, the vital charge carriers that power our devices, are constantly being generated. But at the surface of these materials, they can meet and annihilate each other, losing their potential to contribute to current flow. This wasteful process is known as recombination, and it's a major hurdle to achieving truly high-performance electronics and optoelectronics. Enter surface passivation, a technological hero fighting...
