| Resumen |
We have studied the uniaxial compression of ZnO submicron rods grown hydrothermally over Si/Cr/Au and Si/
Al substrates such as mechanical springs. We used FEM simulations to find the oscillation frequency range at
which the submicron rods deliver the steadiest piezopotential independently of the frequency they oscillate. A
stationary and a harmonic spring-mass model were implemented for a single and multiple submicron rods. We
measured dimensions and submicron rods/μm2 with our SEM/FIB image analysis. Nanoindentation was used to
extract the spring constant and the Young's Modulus of the submicron rods. The steadiest piezopotentials
(±3.72,±5.16 μV) were obtained below 500 kHz. The methodology described can be helpful to design multifrequency
nanogerators |
