High output nanogenerator based on assembly of GaN nanowires.

چکیده
GaN nanowires (NWs) were synthesized through a vapor-liquid-solid (VLS) process. Based on structural analysis, the c-axis of the NW was confirmed to be perpendicular to the growth direction. Nanogenerators (NGs) fabricated by rational assembly of the GaN NWs produced an output voltage up to 1.2 V and output current density of 0.16 µA cm⁻². The measured performance of the GaN NGs was consistent with the calculations using finite element analysis (FEA).

متن کاملIdentifying individual n- and p-type ZnO nanowires by the output voltage sign of piezoelectric nanogenerator.
Based on a comparative study between the piezoelectric outputs of n-type nanowires (NWs) and n-core/p-shell NWs along with the previous study (Lu et al 2009 Nano. Lett. 9 1223), we demonstrate a one-step technique for identifying the conductivity type of individual ZnO nanowires (NWs) based on the output of a piezoelectric nanogenerator without destroying the sample. A negative piezoelectric ou...
متن کاملHigh-output nanogenerator by rational unipolar assembly of conical nanowires and its application for driving a small liquid crystal display.
We present a simple, cost-effective, robust, and scalable approach for fabricating a nanogenerator that gives an output power strong enough to continuously drive a commercial liquid crystal display. Utilizing the conical shape of the as-grown ZnO nanowires, a nanogenerator is fabricated by simply dispersing them onto a flat polymer film to form a rational "composite" structure. It is suggested ...
