Thinner Nanowires Exhibit Giant Piezoelectricity – 100 times greater Piezoelectric effect
Northwestern University researchers have found that piezoelectricity in GaN and ZnO nanowires is enhanced by as much as two orders (100 times larger)of magnitude as the diameter of the nanowires decrease. “This finding is very exciting because it suggests that constructing nanogenerators, sensors and other devices from smaller nanowires will greatly improve their output and …
