"silicon-based pn diodes waste energy as heat... gallium oxide-based electronic devices much more energy-efficient but their diodes require both n-type and p-type layers to function properly... gallium oxide accepts atoms needed to create n-type layers/ rejects atoms required for p-type... overcome with both types working together: shooting nickel atoms into gallium oxide layer, heating at 300°C with activated oxygen radicals and then at 950°C in oxygen gas... standard equipment/ processes, scalable... EVs, renewable energy"
