Wide Bandgap Semiconductor One-Dimensional Nanostructures for Applications in Nanoelectronics and Nanosensors

Wide bandgap semiconductor ZnO, GaN andInN nanowires have displayed the ability to detect manytypes of gases and biological and chemical species ofinterest. In this review, we give some recent examples ofusing these nanowires for applications in pH sensing,glucose detection and hydrogen detection at ppm levels.The wide bandgap materials offer advantages in terms ofsensing because of their tolerance to high temperatures,environmental stability and the fact that they are usuallypiezoelectric. They are also readily integrated withwireless communication circuitry for data transmission
