Transfer technique produces wearable gallium nitride gas sensors
Atlanta GA (SPX) Nov 16, 2017
A transfer technique based on thin sacrificial layers of boron nitride could allow high-performance gallium nitride gas sensors to be grown on sapphire substrates and then transferred to metallic or flexible polymer support materials. The technique could facilitate the production of low-cost wearable, mobile and disposable sensing devices for a wide range of environmental applications. Transferring the gallium nitride sensors to metallic foils and flexible polymers doubles their sensitivity to nit ... read more
