A new material with light absorption characteristics ideally suited for making chemical fuels from sunlight was created via a nanowire growth strategy that fused the semiconductors silicon (Si) and gallium arsenide (GaAs) together in a new way. The GaAs nanowire array increases optical absorption by trapping the incident light and has potential for high solar energy conversion efficiency.
