Toward Quantitative Measurements of Piezoelectricity in III-N Semiconductors Nanowires
Toward Quantitative Measurements of Piezoelectricity in III-N Semiconductors Nanowires
Piezoelectric semiconductor III-Nitride nanostructures have received increasing interest as an alternative material for energy harvesters, sensors, and self-sustainable electronics, demanding well-clarification of their piezoelectric behavior. Despite the feasibility of piezoresponse force microscopy (PFM) to resolve piezo-responses at the nanoscale, several difficulties arise when the measurements are performed on low piezo-coefficient …
