Front Cover: Spatial Distribution Control of Room-Temperature Single Photon Emitters in the Telecom Range from GaN Thin Films Grown on Patterned Sapphire Substrates (Adv. Quantum Technol. 2/2025)
In article number 2400177, Yong-Hoon Cho and co-workers controlled spatial distribution of room-temperature, telecom-wavelength emitting single-photon emitters (bright red colours) based on defects in GaN thin film grown on patterned sapphire substrates with varying pattern sizes and dimensions. This approach effectively controls the position of emitters between patterns and enhances the photon extraction efficiency via pattern size optimization.
